I will go ahead and throw my two-cents in here too. I am one of the "straight" guys whom ilffer had mentioned who had went to him for something that I "wasn't getting at home..."
I like getting enemas, colonics, and prostate massages and while there may be some services available for one or some, what I get from Dan equals nothing that I've experienced anywhere or from anyone else.
I believe that enemas and prostate massages are good for my overall health and sexual well being... I feel fortunate to know a person that is very good at both and enjoys the processes as well. The best person whom I have found who is willing to indulge me in this manner happens to be another male, and I am very okay with that.
