When I was first dating anal sex in the hetero community was relatively unheard of of rarely mentioned. Nowadays it is obviously much more prevalent. What percentage of the women you have dated are up for anal sex? Do you find that the younger they are the more likely they are to participate? In my experience age has had little to do with it though it seems women 10+ years younger than me seem more experienced at it than the women above that age. Also to answer the first part of the question my experience has been about 30% of my partners are up for it. Also interesting that the first gay man I ever met was not an anal sex fan. What percentage of the gay/bi men you are with decline anal sex?
