I believe I've posted some of this information on a previous thread, I made a trip to the Los Angeles area in, I believe, 1985, with the goal of visiting the Sherema Clinic, and The Chalet, the latter being a well known S&M Parlor. I have forgotten how I learned of these two kinky places, likely from ads in an adult magazine. I will confine my reply to the visit to Sherema, it was, as a few others have noted, a bit rough looking on the outside.
I was buzzed in and welcomed by a slender blond, dressed rather scantily in a nurse's uniform, garter belt, and hose, She reviewed the list of services available, and I opted to receive a large volume enema series from her, which included prostate massage, and several different nozzles, the last being some double inflatable.
Although it's been many years, I have fond memories of the clinic, and her ministrations. Mutual touching was allowed, and after we got better acquainted, encouraged. After a brief rest, I opted for a session with a very attractive brunette girl, only this time I gave her several enemas, and I was amazed at her capacity to hold a fairly large volume enema, and to enjoy, or at least appear to enjoy the entire process. Again, mutual touch was encouraged, and it was, at that time of my life one of the most erotic experiences I'd enjoyed. Sadly, I didn't have an opportunity to return to The Sherema Clinic for a second visit before it closed.
