I know Ray and have been to a couple of these, but not the DC ones.
The parties I've been to are a ton of fun, less pretentious crowd, lots of action, just a much more chill environment. I've had a great time.
The porn stars that headline the event end up playing and it's not a performance, they are part of the action and lots of different types of guys take part. And it is a good way to meet and interact with the guys before a hire, I certainly found a couple of them much more my type in person than I thought from their ads. Getting to both talk with them and get to know them in other ways as well... 🙂
