You can actually buy life like sex dolls. They'll even do the eye colour, hair and body shape and have them wear lingerie. The vagina apparently feels real or close to it and you can even do a-nal and oral sex. Will cost about 3-4 grand though.

I will say that if you get one, would be a good idea to not let your future GF know about it. Some women will (unfairly) be creeped out by it.
