Maybe I should just bite the bullet and ask him
Most (but not all) of the OF guys are open to escorting for men, but there are a LOT of factors at play — negotiating a price; service expectations (is it just a blowjob, are you guys having sex, is he spending the night etc.); are you paying for his travel; is there an NDA agreement, etc.
But another factor that is completely out of your control is the guy’s interest or need at that moment. Say for example if he’s just incurred some big expense and needs money asap, your message could be timely and he would be more agreeable than, say, him having just gotten paid by another client or receiving his tax refund (lol). He may not be as hungry for money at the moment.
Also, these guys don’t like back and forth messaging; the fewer messages, the better. Be upfront with your ask and offer from the get go.
Nothing to be scared of! Shoot your shot! You won’t be the first or the last. The worst that can happen is that you get ignored lol.
A note tho: Contrary to what some here think, I honestly don’t think Kane/Duke is into men AT ALL. So you will need to offer him big money that would be hard to say no to (like over $1k). A couple hundred dollars isn’t gonna cut it. And that’s exactly the problem. The guys can be bought, but most people can’t afford them.
