When I was at school there was one book that was read more than any other in the library. It was 'Forever' by Judy Blume. And there were a couple of pages in particular that were quite worn... you guessed it, the pages about sex.
Personally I don't actually love graphic sex scenes in novels. I prefer the author to leave it up to the readers' imagination as to what's happening, but when it comes to kissing I prefer full emotional and physical details! Do I have double standards? I don't think so. I actually think that making love is a very personal and emotional experience that gets thrown into too many books, just because. I like it to be there for a reason, not just a page filler.
I also think movies have too much sex without enough of the responsibility. Do the characters ever use contraception? I think we, as authors, have to promote safe sex at least. Unless getting pregnant or a STD is part of your story.
Anyway what are your thoughts?
