Not sure where this post belongs, but I wanted to share what I discovered that works WONDERS for masturbation for transmen. I am a married guy, but my wife doesn't seem to enjoy giving me ->-bleeped-<-s, but I LOVE getting them. Having an affair is not an option, but I got to the point of NEEDING a ->-bleeped-<-. I searched for months to find some sort of way to mimic a bj. I had tried the water bottle with warm water method, but I didn't get much out of that. I had bought a sleeve, but even occluding the other end didn't provide enough suction. I was too afraid to use the vacuum to get sucked. I was cleaning our room up one day when I found some old CPAP tubing an decided to put a sleeve over one end and suck on the other. OMG was I ever glad I did!!! Not only did I climax super hard, but it was by far the most satisfying solo orgasm I have ever had hands down.
