Does excessive masturbation have any bad effect on erection ?

I really don't think so! I've been jacking off frequently since I was 12 and I'm 65 now and have no problems at all springing boners. I think there is something to that old saying "Use it or lose it!" in fact. Recent evidence has backed me up...if you keep sexually active, you'll keep sexually interested...in other words those boners will just keep coming (no pun intended!). Just do it as much as you want...no side effects at all to jacking off!

Excessive masterbation has NO bad effect on erections.

Enjoy!

The only one I know is that you may not be able to do it too many times in a day! :)
