Re: how come my testicles are swollen after masterbation?
First of all, there is no connection between your abs disappearing and masturbation. Your abs will not go away that fast and masturbation will never be the cause. Try looking at yourself from a different angle to see if it was just a bad angle.
When it comes to your testicles swelling, it can happen if you are hitting them in the process of completing your activities. Some also swell a bit after they release semen. As long as the swelling goes away and you do not have pain, you should be fine.
