Hey BBG! I have one, and he's a doll :) I'm single, he's single, we hook up now and then for hot sex and that's it.
We met on Adult Friend Finder - there are a lot of people looking for that kind of relationship on there, might be worth a go for you!
Tips? Don't do sleepovers, always be super-safe, and continually reaffirm the boundaries of the relationship - you never know when either person might develop feelings so it's best to talk about it often.
Pitfalls? Developing feelings! I'm a big softy, so I totally fell for a previous fb... got a bit crushed when I realised he was seeing other people too. This could also be a problem if you've got a possessive streak.
Benefits? Hot hot guilt-free, sleep in your own bed afterwards sex.
I say go for it!
