This first is from an ad on TW, Femskin
It's not yet lcear to me if the vagina is cosmetic or functional. Unless I missed it in reading the site a major omission for them. One could infer it is cosmetic if they don't say otherwise. In any event, you are talking silicon and $1300+ for "cadillac" level materials.
This is a latex product:
Considerably cheaper, in the $450-300 range, but....lates isn't silicone. There is a reason the most realistic breast forms are made from silicon...actually a few reasons. (There is a nice non-silicon form that you can sleep in and cut without destroying it at under $100) This second product clearly states it is made to have simulated intercourse with and is designed for telt contact through the latex wall of the appliance.
this link shows both types of material, the (non femskin)artificial vagina is pictured on it
Search the web before you buy. Prices can vary a lot between sites. Hope this is what you needed.
You might want to read the tutorials for Google. I get a lot done fast with search engines and you will love all the items you can find by surfing from a Google search. Hint: using the "without the words" slot can eliminate a lot of garbage in searches. Putting "XXX" "porn" "pics" in that slot can keep TG/TS searches out of porn sites and on factual sites.
