What Can Sex Dolls Do? Capabilities and Limits
A sex doll can hold a pose, stand on bolted feet, warm to roughly body temperature, speak recorded lines or app-generated replies, and be customized in height, face, skin tone and hair. It cannot walk, move unaided, or stay warm without a power source. That is the honest short answer.
The feature list grows with price. A $400 TPE torso and a $3,500 silicone figure with heating and voice share a category but little else. What follows is what each capability means in daily use, what it adds to the bill, and where the limits sit.
1. Silicone Material Introduction
The skin layer sets the ceiling
Almost every capability traces back to the outer skin. Platinum-cure silicone and TPE both imitate skin but behave differently under heat, pressure and dye. Silicone holds detail longer and resists staining. TPE feels softer out of the box, costs less, and needs more frequent powdering.
Neither material warms itself. A figure in a 20 °C room feels like 20 °C, and the surface needs 20 to 40 minutes of contact to approach skin temperature. Heating hardware changes that; the material alone does not.
Our breakdown of silicone vs tpe sex doll construction covers chemistry, repair options and long-term wear in more detail.

Weight is the number buyers underestimate. A 160 cm silicone figure at 38 kg is heavier than most people expect to carry upstairs, and that weight decides how often you re-pose it. TPE at the same height usually saves 4 to 8 kg.
Articulation sits underneath the skin, so one body mold can feel stiff or fluid depending on its frame. Our guide to sex doll skeleton types explains friction, locking and hybrid joints, and why joint count alone tells you very little.
2. Customization Options
Head, face and hair
Most full-body figures ship with a removable head on an M16 thread, a fitting shared by many makers. That decision unlocks face swaps: a body ordered with two or three compatible heads behaves like several figures for a few hundred dollars more. Wigs, eyes, lashes and makeup are usually fixed at order too.
Options vary. A maker may offer 3 to 12 skin tones, several eye colors, and implanted or wigged hair. Implanted hair photographs better and is harder to clean; wigs are cheaper, replaceable, and better if you want a different look every month.
Where a catalog is flexible, order through a custom sex doll configuration rather than a stock build. Expect 3 to 6 weeks longer and a deposit that is usually non-refundable.
Body specification
Height is fixed by the mold, so the range runs from about 100 cm to 170 cm for full figures, with torso-only pieces shorter. Cup size, hip width, shoulder breadth and leg length follow the mold. Surface detail is what you can vary: body hair, freckles, stretch marks, tattoos, nail color and standing bolts.
Electronics: heating, voice and app control
Heating is the option most buyers use. A rod or blanket raises surface temperature to 35 to 40 °C in 20 to 30 minutes, and the warmth fades within about an hour of switching off. Built-in elements cost more and cannot be removed if they fail.
Voice modules play recorded phrases on touch or remote command. App pairing over Bluetooth typically reaches 10 to 20 m and adds scripted replies, sound packs and firmware updates. Our overview of the talking sex doll category sets out what these modules can and cannot discuss.
3. Buying Guide
Start with the job, not the spec sheet
The capability you need depends on the job. Display and photography reward detail, stable standing and a good wig. Companionship rewards a size you can lift and a frame that re-poses easily. A 170 cm silicone figure bought for a third-floor walk-up is the most common mismatch we see.

A five-point pre-purchase checklist
Confirm the joint count and, specifically, whether the knees and hips lock. Locking joints hold a raised pose; friction joints drift.
Ask for the shipping weight and carton dimensions, not just the product weight. A 160 cm figure usually ships in a box around 155 by 40 by 30 cm at 35 to 45 kg total.
Decide on standing feet before production. Bolted feet cannot be added later without replacing the leg cores.
Confirm the head thread and whether spare heads are stocked, since a second head is cheaper at order than as a separate purchase.
Get warranty length, defect definitions and who pays return freight in writing before the deposit clears.
Ask for photographs of the exact build, not catalog renders. A maker who cannot show the shipped item, or who quotes a 160 cm silicone figure at $600, is usually describing something else. Our sex doll posing guide walks through the ranges each joint actually holds.
4. Maintenance & Care
The 20-minute weekly routine
Wipe exposed skin with a mild, unscented soap and water below 35 °C, rinse with a damp cloth, and dry fully before storage. Internal channels need a separate pass: flush, drain, then air-dry for 2 to 4 hours with a drying stick or low-powered pump. Trapped moisture is the single most common cause of mold in TPE.
Powder, oil and heat
Powder every 2 to 4 weeks with plain cornstarch or a dedicated doll powder to cut surface tack. TPE benefits from a light mineral oil wipe every few months; silicone does not need oil and should not get silicone-based products. Store below 30 °C, away from radiators, and never in a car or sunlit room where surfaces can pass 50 °C.
What actually shortens lifespan
Storing a figure upright without ankle support, which slowly deforms the feet.
Dark clothing left on for weeks, which transfers dye into both materials.
Sharp jewelry, zippers and pet claws at the hips and knees.
Carrying a 35 kg figure by the arms or neck instead of the torso and hips.
Ignoring a small tear until it reaches the frame.
A repair kit matched to the material costs $25 to $60 and handles most small cuts. Frame damage is different and usually means a new figure.
5. Shipping & Privacy Policy
Packaging and billing
Figures ship double-boxed in plain corrugated cartons with no product imagery, brand marks or contents listed outside. The billing descriptor is a neutral company name, not a product description. Packaging is discreet by design, but no retailer can guarantee absolute anonymity against someone tracking the shipment itself.
Timing and tracking
Stock items usually leave a warehouse in 2 to 5 business days, and delivery runs 7 to 20 business days depending on destination and clearance. Made-to-order builds add 3 to 6 weeks before dispatch. A tracking number is standard, and a signature is usually required for boxes over 25 kg.
Import and paperwork
Duties, taxes and restricted-item rules are set by the destination country, and they change. Some countries treat full-body figures as adult goods with specific clearance requirements; others apply standard duty. We supply commercial invoices and material descriptions, but we cannot promise a clearance outcome, and duty is the buyer's responsibility. This is general information, not legal advice; check your own customs authority before ordering.
6. Trust & Guarantee
What a warranty should say
A written warranty normally covers frame and joint failure for 12 months and skin defects present at delivery for 30 to 90 days. Wigs, eyes, lashes and heating rods are usually excluded. A vague lifetime guarantee is a warning sign, not a selling point.
Returns and defects
Hygiene rules mean opened figures are rarely returnable for a change of mind, which is why specification errors cost so much. Defects are different: a seam split, a collapsed joint or the wrong skin tone documented in photographs within 48 hours should be covered by repair, a replacement part or partial credit. Read that clause before you pay.
How to check a seller
Look for a physical address, a working phone number, terms naming a jurisdiction, and photographs that match the stated specifications. Response time matters more than review count. Ask one specific technical question, such as the frame material or head thread size, and see whether the answer is precise.
Frequently Asked Questions
Can sex dolls move on their own?
Standard silicone and TPE figures cannot move without help. Their joints hold a pose once you set it, which is a different thing from powered movement. A small number of robotic models add motorized hips, heads or limbs, and those cost several thousand dollars more, weigh more, and introduce batteries and firmware that need servicing.
Can a sex doll stand upright?
Only with the right feet and a stable, flat surface. Standing feet use threaded bolts that extend through the sole, and they let a figure balance without a stand. Without them the ankles cannot take the load. Even with them, keep one hand on the figure while you position it, and never leave it standing where it could be knocked over.
Do sex dolls produce their own body heat?
No. Silicone and TPE sit at room temperature, roughly 18 to 24 °C in a typical home, and warm slowly from contact. Optional heating rods, blankets or built-in elements raise surface temperature to about 35 to 40 °C. That warmth usually lasts 30 to 90 minutes after the heat source is switched off.
Can sex dolls talk?
Some can, within limits. A talking module plays pre-recorded phrases triggered by touch or a remote, and app-connected models pair over Bluetooth to generate replies. The voice is synthesized and the conversation is scripted or model-generated, not spontaneous. Expect the feature to add $100 to $400 and to require charging and app updates.
How many joints does a sex doll have?
Most full-body figures use 16 to 28 joints, with the count rising at taller heights. Load-bearing joints sit at the shoulders, elbows, hips, knees and ankles. Locking joints hold a pose under weight, while friction joints move more freely but sag. Ask for the joint count and whether the knees and hips lock before you buy.
Can you customize the height and face of a sex doll?
Partly. Height is fixed by the body mold, so you choose from what a maker offers, usually 100 to 170 cm. Faces are more flexible: many bodies accept several compatible heads, and wigs, eyes, makeup and skin tone can be specified at order. Fully bespoke sculpts exist but cost far more and take weeks longer.
Are sex dolls waterproof?
The skin is water-resistant, but the figure is not submersible. Water gets into the neck joint, the head cavity and any electronics, and trapped moisture inside TPE encourages mold. Wash at a sink or in a shower with a spray head, keep the neck opening dry, and dry internal channels within an hour of washing.
Can a damaged sex doll be repaired?
Often, yes. Small cuts close with a repair kit matched to the material, and joints can sometimes be tightened through the access point at the back. Head, eye, wig and hand replacements are straightforward on modular figures. Frame damage at the spine or hip is the usual write-off, since repair means opening the body.
Do sex dolls need charging or an app?
Only models with electronics. A plain silicone or TPE figure has no power source at all. Heating, voice and app modules add a battery or mains adapter, a charging routine and firmware updates. Ask what happens when a module fails, because the figure itself still works once the electronics are switched off for good.
How long does a sex doll last?
A well-kept silicone figure commonly lasts 5 to 10 years, and TPE typically 1 to 3 years before it turns tacky, tears at stress points or loses shape. Storage temperature, powdering frequency and how much weight the joints carry matter more than the brand name. Heat above 40 °C and direct sun shorten life quickly.
Final Thoughts
The honest capability list is shorter than marketing suggests, and more useful once you know it. A figure poses, stands, warms, speaks on cue and can be built to specification. It does not move by itself, it does not generate heat, and every electronic feature is one more part that can fail.
Spend the budget where you will notice it: a frame that locks at the knees and hips, a height you can lift, and a material you will maintain on a schedule. Those three decisions decide whether the figure gets used weekly or stored in a closet.
