There are full size silicone child dolls that are not for sex, but I don't think we're allowed to talk about any full sized silicone dolls at all even if they aren't sex dolls? Something about them being too eerily realistic or something I was told.
The Lovely Dolls from ATdoll is what I have, so that's what I garnered the information in my post from.
The Phicen and Hot Stuff Edation dolls (I have an Edation one too myself) are made of a harder silicone and separates more easily at the seams. I was rather disappointed with mine.
The skeletons are not wire, but a combination of plastics and metal with hinges and pivots. I haven't seen any high end silicone dolls that have only wire frames yet, although some have wires for fingers and toes.
Here are some pics of the inside of the skeletons in the Phicen (right) and Edation (left) dolls, from this page:

, but they are way stronger and seem to be more complex. My Edation doll's poses are stiffer and far more limited than my Lovely Doll is.
