Masturbation during Exercise

I have a friend who owns a private gym and every day around lunch time he closes it off and uses it exclusively for himself and a few others. They do what he calls 'testosterone building'. They work out with an erection to keep the testosterone level high. They're gay so they don't mind taking turns helping keep each other erect. At the end of the session everyone does something called kegels then ejaculates. A few ejaculate during the work-out too but most refrain and just do it once at the end. He knew several other private gyms that practiced this so it appears to be fairly common.
Although I'm not gay, I have no hangups and it seemed to make sense. He has a strict 'no sex' policy, hands only, so I joined in a few times to give it a try. I could feel the difference in only a few sessions and have been an avid member for 6 months now.
Only possible downside for me is that my appetite for ejaculating has grown as has my overall libido which I have to attend to. This is the opposite of what I would have expected. I'm also surprised how hard another guy could induce me to ejaculate even though I'm straight.
With the risk of drugs in sports, why don't we hear more about this option?
