I don't see anything wrong with guys wanting a face pic. Asking for it a few times doesn't make him a 'boundary pusher' in my opinion.

I mean most don't want a 'blind date' and if it were me I'd definitely want to see a face picture before I agreed to handing over large amounts of money.

Feedback isn't everything, but it definitely helps me feel more comfortable especially when there's lots from well established girls. You might well have missed out on a good booking because of it, but it's your decision at the end of the day, and if you're adamant about not showing your face then that's your choice and there are plenty of guys that will obviously see you without it. Happy days
