Yep true, that makes sense. The story I'm currently working on, is a horror thriller, with a rape in, that leads to revenge later, but I was told that the rape scene was too distasteful and gratuitous to show, and that I should cut it out and have it only be implied. So I followed the advice of some of the readers and cut it, but not wondering if I should put it back in, since maybe this kind of thing needs to be shown in a thriller to get more of a reaction, for the revenge later.

As for teen romance, yes I would say don't write the sex, unless their is something peculiar or especial about the relationship that demands it. I thought my example of Pumpkin (2002), had such a peculiar relationship in it, that it sex should have been shown, because of the peculiarity of the relationship.
