Been at it virtually every day since before I can remember.

Only time I missed was one day when I had my tonsils out.

Twice a day and love chatting to guys when they wank too. Best hobby in the world

i wank far more now than when i was a teenager....2-3hrs a day

I prefer edging when I stroke my cock. I work it everyday, multiple times a day on the weekends, and have done so for years. Enjoy!

According to my records, I have to say that the frequency of masturbation has steadily decreased from an age of 29 years.
I am now 74 years old and masturbate regularly ie daily since I was 9 years old. (I regularly masturbate three times a day for many years.) That's 65 years. In that time I have masturbated about 27 595 times. Even now I masturbate on average 1.2 times per week. Therefore I have the exact figures, because I brought out of interest a sex diary. Check out times at the link, I'm Mr.Z.

I once tried to get along (out of interest) without masturbation at the age of 23 years, 21 days I have endured, it was hell. I kept exactly 21 days while experiencing my first and only nocturnal pollution.
By the way: Adverse health effects I have not found until now. So do not worry.
I masturbate even better than I had sex with a woman
