@Nezushi, I think 30 minutes after I finished posting, I also thought of Ameiro Paradox too! And they do it in a public restroom and in the shower! lol. I feel pervy for remembering, but it's one of my favorite yaois, so I've read it a couple of times. And yup, sex occurs so often in yaoi and bathrooms are pretty much prime do-it spots that unless it was particularly memorable, it's also quite easily forgettable too.
