He can still partake in the hobby. I have a client who is exactly like that. The only time we have sex is when we go away for an overnight which is about once a month, the rest of the time we are going to dinner, watching movies at my place, cuddling, kissing, giving massges to each other and other intimate things. It took six months before he was comfortable enough to even go on an overnight, and we see each otehr every week. It just takes time, that is what real GFE escorts can provide, but of course time is still paid for. So if he can get over that then research some really great GFE escorts in the area that he lives in, call and email a few and slowly narrow it down to the one that he feels most comfortable with and then meet for a coffee date. After that, they make the sessions go they way they want, eitehr fast or slow. A professional escort is not going to look at him wierd if he is not jumping her bones when she walks in the door.
Good luck,
