I have other sites I can go to for straight up sex. Even there though, it's hard as a writer to just crank stuff out, without there being context and purpose. Here, however, I'm very open to sex scenes and would encourage them if my partner didn't care either way. Why? Because it only happens when the pair is at that stage where it would mean progress in their relationship. I feel like outlining the intimate closeness (more emotional than physical) provides both characters and writers with a great insight into the story. Each character should react differently to sex, someone else's touch. To me, sex can do wonders for a RP but only if it's timed well. I have done less than five sex scenes on this site (I include the Old Guild too) and that shows that most RPs don't go that far. I would never require a partner to write one with me however. If they're not comfortable, that's fine but in a way, if I know a character isn't going to have sex in even the far future, I can sometimes hinder my own writing. Fading to black feels the same way. How do you write that two people had became intimate when really, they didn't? After you approach the sex scene and skip over it, you need to sum up the consequences (good and bad) of having sex when you just faded to black and for me, without the act, the writing feels somewhat hallow. It can be uncomfortable for many writers to write sex. Some people don't feel it's "okay" morally while others are shy or not interested. That's acceptable, of course. But for me, I'd recommend it if for the sake of things developing more smoothly. Either way, having a frank discussion about character comforts as writer comforts is something more people need to do, regardless of topic. Communication is key to a story going well, no matter the direction it may take.
