OMG. I have NEVER written sex. At all. Ever. First, I don't think people need to have sex to write sex. That's just my opinion though. Aaaaand just because you've had sex, doesn't mean you can write sex either. :P LOL. My bff makes #1 her reason not to write sex for her old Harry/Draco fics. I think she could have though, if she'd tried.
ANYWAY. Um. This is just an excuse to post links. Haha.
I read this YEARS ago, and can't believe it's still there. It was probably one of the first times I'd tried to research on gay mansex and kinks, etc, etc. I didn't know about LJ then.
http://www.squidge.org/minotaur/classic/eroc.html THESE ONES THO. People have got to read for the LOLz. It's just a compilation of bad sex scenes actually published in books. It's straight, just warning you. Like male/female.

http://www.guardian.co.uk/books/2007/nov/27/awardsandprizes.badsexaward Gah. I'm not really helpful.../o\ my only advice is: type "Writing sex scenes" in google and hopefully you'll find something. But wait slash! Right. "Writing slash" is probably better. And study sex. I suggest pornz! XD (Biff, if you're reading this, you should look for porn, and write it, so H and D can finally have sex in your fics... JUST SAYING).
