This topic keeps getting debated but there's no proof to support either argument in the pro- or anti-ejaculation debate.
It's not the orgasm that will set you back, it's the >>ejaculation<<. That's what would, if anything, have the undesired effect of leaving your cock unresponsive for continued work, but why does anyone think you'll >lose< any gains you've made? All you're losing is the pump you had built up. Analogies to muscle training are well and good, but it's truly not the same thing.
When you edge, as Supra and others have so clearly explained, the cGMP and all that fluid buildup makes for a big pump. If you >>orgasm<<, the mechanics will CONTINUE to cause engorgement, even if you go to twenty percent or less erection level post orgasm, you'll bounce right back from an orgasm refractory period. I do this for hours sometimes, for training and for pleasure.
When you >>ejaculate<<, all that fluid and sperm buildup is released, you enter a true refractory period, and then you won't necessarily want to continue if you're like most guys. That's where the problem lies as I see it. The desire to continue is gone and the pump is gone and you're left without the desire to do anymore work.
Until someone proves that it's detrimental to real gains, I'm gonna blow and blow, and I'll tell you, my cock is bigger and fatter than ever even with cumming as part of the routine.
And NOW, thanks to the ROP, the desire to get back in the ring after I cum is stronger. This thing is FANTASTIC!
Damn! Get one now!
