I've never received an enema from a male, and that wouldn't be my preference, but have received quite a number from female friends, and a few from escort/for hire providers. I have made contact in a nearby town with a provider who typically does dominatrix sessions, I found that she worked at a service in New York City for a time, and is very adept at med fet and enemas as well as B & D.
I had a session from her about a month ago that I really did enjoy, she did a sounding session first, being very careful to change gloves often and keep the freshly autoclave sounds sterile. From there, she slowly removed her clothing until she was wearing only 4" heels. In between articles of clothing coming off, I received extensive anal massage and repeated enemas.
I left feeling refreshed and well satisfied, as it's rare to find a woman who really enjoys that exact scenario - at least it has been for me, and I have, and have had thru the years quite a number of playmates. I had a few drinks before calling her to work up my courage, asking about the dressing down part of my session, she said, "sure, I'll do that, if you don't ask, you don't get" ....so work up your courage guys, and ask politely. I will report that she is completely shaved, and very attractive for her age. ?
