This can have unaticipated consequences. I once convinced a GF to do anal, and she loved it. Thing is, I didn't like it all that much after I convinced her to let me do it. She wanted it all the time and everytime we had sex it was "fuck my ass...fuck my ass". I mean damn, it's like #3 on my list of favorite holes. She ran off with some asshole who I suppose is still banging her in the ass...
