Apparently, I read that building up semen volume does result in bigger balls and bigger penis due to the production of testosterone. Has anyone noticed any increase in testicular volume after abstaining from orgasm? I'd like to hear about it. In addition, I notice that the more excited I am, the firmer the testicles are. I think firm testicles mean that the testicles are in the process of producing testosterone. Anyone care to talk about their experience with these?
