When I started experimenting with myself - with perhaps 13 years - everything aroused me like hell. I remember one time alone at home masturbating one entire day - coming around every halve hour - so it must have been around 20 times. The second result was that I couldn´t touch my tool during some few days after.
But that is loooooong time ago. Today I am happy with three, four times. More would be real hard work. But instead I can have my multiple ones (on good mood days only), that is finally much better.
