Ever since I was 17 I've been seriously wonderin about the ejaculation - testosterone relationship. I've read all the science, about the increase and decrease in levels prior and after. But in the end, let me offer what 4 years of experimenting has yielded.

(Btw, I'm not kidding. I have tried to eliminate as many variables as possible on repeated occasions just so I can isolate the effect.
The Inspiration:
One day, years ago, on a boring afternoon, armed with a new internet connection and an empty house, I liberated myself 4-5 times. Later that evening, in the gym, each side of my body was stronger by roughly 10-15+ lbs. Combined bench went up by over 30 lbs. I had no initially made the connection, until I realized later I could no longer perform close to the same weight. That was an isolated time.
The hypothesis:
Wackin it increases testosterone and subsequently strength. Natural PH u might say.
Conclusion:
WRONG. In fact, upon each trial, I was *decisively* more fatigued in lifting post-"playin with it". (By fatigued I mean low lifting intensity, endurance, as well as decreased overall explosive power.)
New Experiment:
If I make absinence the norm, (no ejaculation same day or prior to lifting), and ejaculation the weaker end, then sexual stimulation WITHOUT ejaculation must be a new scenario that needs testing.
Result:
JACKPOT!!!! I guarantee this to anyone right now. Million dollar challenge. If any of you spend half an hour watching very good porn, or engaging in foreplay with your woman (better result than any self-stimulation), your gym results for that day will be phenomenal!!! Whatever you expected to do that day, given the diet and sleep, will increase like you just took a super PH supplement. I kid you know. I warn you, this takes discipline. If you accidently decide to cum, you'll make yourself so tired and weak you'll ruin the gym session.
Conclusion:
The amount of testosterone and other chemicals (adrenaline, etc.) stimulated through sexual arousal are unrivaled for an immediate strength boost. The more aroused you are, for longer the duration, is directly proportional to the curve of increased performance. In math terms, you can express the benefits of strength from the increased testosterone as a function of horniness. (not the general frustrated kind, but maaaajor blue-ball.) If you all think I'm wack and have too much time on my hands (no pun intended x 2), try it for yourselves. If I have the time, this ritual is almost religious. Try it the day before your max-press, and post your results here.
