Do silicone sex dolls feel real?

They feel firmer than TPE, and which one reads as more realistic depends on what you are judging. Silicone has a resistance closer to muscle than to gel, and it holds sculpted detail in the face, hands and feet that softer materials lose — so it looks more convincing, especially up close and in photographs. TPE gives more, so it feels softer in the chest and thighs. Buyers who prioritise visual realism generally prefer silicone; buyers who prioritise softness generally prefer TPE.
