I use to do it everyday and sometimes more than once a day during my younger days. The drive is just too high which I do not know if its just me or its the same with most young men.
Slowly when I grow towards middle age (40), I found that if I wank everyday, I can't perform well when I really need to use it. Ha ha...
So from there, I avoid wanking myself, and if I have the urge, I find myself something else to do to divert the thoughts away.
