If the guy is supposed to bottom, I am not sure I care that much if they are hard the whole time. But if they are supposed to top, it's an issue. I cannot say that I am 100% reliable on this front (but then I am not the one being paid).
Absolutely not. There are other ways to deal with specific security concerns (and I may have asked exactly what those concerns were). Did he volunteer to provide his full name in return?
I was in a scene with two guys I hired and while one of them had his arm in the other's ass they asked me to take a pic and send it to them. A few days later the photo was (and still is) on their RM profile. LOL....I always get a kick out of it when I see it.
I have met him before (in a purely social context) and he seemed like a really nice guy. And if you are looking for the "daddy" type, he could be a good choice. But $400 still seems a bit steep to me.
