Oh, as for pricing, the typical "arrangement" is a weekly or monthly allowance. There's lots of variances: how often are you meeting, are you exclusive with each other. Those are things that should get talked about pretty early on.
Then there's Pay Per Meet, or PPM. More transactional, I've gotten used to it, but I don't really like it, but it's good for starting out. I guess if I was having sex on a PPM basis, I would be really uncomfortable, but it hasn't happened yet.
And I guess I should say, I've only been back at this for about a month, and I've had a lot of dates, but I have yet to sleep with anyone. I would guess most guys are more aggressive that way, but I want to like someone before I have sex with them, not just lust after their body.
