In the early 2000s I'd go to a guy in south London who gave enemas. I was in my early to mid 20s, he offered them on a gay chat site. I started with him, a session every couple of months, 2-3 enemas a session, soap then salt.
I have only had enemas as a consenting sexual / medical grown up experience. There's a feeling of being cared for and guided through it. The guy was a gentleman and never watched me expell. I had the occasional enemas from male play doctors before a rectal exam or use of proctoscopes, but my enemas guy was mainly about giving enemas, not broader medical play.
Around 2010 I bought my own equipment.
Parallel to having equipment I was chatting to a guy I want as my doctor. It's all a bit wizard of Oz, but I want the man behind the curtain.
I made the mistake of offering him the right to tell me when to have enemas. Any sub would love that. An online consultation followed. I have no "need" for enemas, I'm vegetarian, I did them for fun / abuse / perhaps help with weight.
My DOCTOR forbade me from ever having an enemas again. This was in 2013 and I have followed his orders for 12 years. I dumped the equipment. I sometimes look it up online, I could easily order it, might even have a wank while thinking of having an enema session again. It's a bit twisted because I could have them behind his back, but this is one abuse I can (not) take for him.
