I stumbled on this thread from last year on Reddit recently: https://www.reddit.com/r/sex/comments/3a8qzr/question_what_do_you_like_most_about_sex/ For some reason, I find this question and the subsequent answers fascinating. Obviously there's whatever you like physically, but that's not what this is asking. I think it's trying to ask why do you like it. Focus: What is it, apart from getting off, that you like the most about sex? Alt focus: What's your least favourite part about it? Who knows if this has legs or not...it's just an interesting question.
