I've been trying to research this but I'm having a hard time finding specific information on this.
I can't tell if less sex/masterbation lowers or raises testosterone levels -- when you go for a while without it, you feel a build up of aggression and of course arousal, is this a result of raised hormone levels? of course it could be the complete opposite -- without regular sexual exercises testosterone may drop.
Anybody know the answer to these? also in terms of hormone levels is sex any different from masterbation?
