Tough to say, as it's not my area. From what little I know, guys like your bf might still be in heavy demand in the pay-for-splay game, but they're also in heavy supply. Also, in general, the less attractive the client (physically and emotionally) the higher a price you can command. Pulling numbers out of my ass here, I think you might get $75-100 from some random guy at a bar if he was lonely, desperate, and financially solvent. You might get $200 out of one who was especially all three, but at that point, he's probably just ordering online instead of hoping against hope at a bar.
And I read nothing in the OP other than idle curiosity. I've wondered if I'd be able to make money sexually (no), or what I'd "order" if , say, I were given some sort of "gift card" for some escort service. I think it's the same thing.
