Sorry, I'm getting ever so slightly pissed off by the dozens of pointless (!) masturbation threads (why do people always open a new one anyway, why not continue where we left?). I believe what you describe sounds like a psychosomatic condition (i.e. it's in your mind, a sort of nocebo).
But if anyone feels like continuing this discussion with more than baseless speculation and on a more scientific level, provide serious references. If not I beg a mod to close this useless topic (or merge it with the millions of other such threads). I find it is extremely irresponsible to repeat the same, old, tired myths again and again. No one will be helped that way.
Only two posts in one thread and we're already at 2 myths:
-) prolactin rise is minuscle and transient, almost 0% change in AUC over 24hours.
-) the loss in zinc is minimal at best, probably similar to sweating, but then again, no one feels depressed from sweating...
