Well I can see why the OP has an issue with the process, but here's the reality. In this business, you have to expect some "ghosts" occasionally.
People who book and back out last minute. I don't usually have a problem with a regular client doing that. Some new clientele will naturally pull
it.
If you have an RM account, you likely have nudes. I always have had. I have no problem with a prospective client seeing me nude via photo before we meet. I suppose I'd rather he pay for it via "Only fans", but I don't have an OF account at this point. Limit the nude photos to one or two if needed, always make sure the photos are recent, clear and honest and move along.
