I have used escort services about a dozen times. I always let them know what I want when I call because some of them want nothing to do with enemas but many are ok with it. I have only had two or three sessions, however, that were really super great. Usually, they are only so so experiences and they always want what I consider a lot of money. Some will say they need more money to give an enema, and I know right then I don't want their service. In my opinion, giving an enema should be easy money for someone whose work usually involves having sexual intercourse with total strangers.
A better alternative is a professional dominatrix. Again, not all will give enemas, but the ones that do know just what they are doing! In contrast to escort services, my experiences with dominatrix enemas has been all positive, and the cost is usually less. These women are professional and understand what guys like me are looking for.
For these reasons, I have totally sworn off escorts.
