I've been a long time user of RHP (on and off) and I've had a lot of good times. RHP is probably one of the more modern looking adult dating sites and easy to use. I never had trouble meeting people on there. Not sure how it is with single guys (it's always hard for men) but I know quite a few men at least that are happy since they met me ;)
Easy to use. Lots of sexy people.
Some inactive profiles get in the way of searching for hotties. No biggie.
