Human sexuality have evolved since man first discovered the poontang and seemed to get bored so he wanted to get some head and lick the clit, then he wanted to get up in the butt hole.
Now the future of sex for both men and women, is moving towards cyborg coitus. Why? Maybe it's because there is no fight to get freaky in any hole and no disease transmission. Plus the borgs come in all ethnicity, body size, height and a whole range of other crazy actions. To some it's bizarre, but to those who spend up to $6k for a sex doll, it is the best money spent.
