I think that masturbation is a sexual orientation of its own.
Like heterosexual, gay, bisexual or similar?
For me, masturbation is the most enjoyable and important sexual activity. although I am married. I'm a masturbant and masturbate rather than having GV.
I am 72 years old and masturbate regularly since I was 9 years old. (For many years I have masturbated regularly 3 times a day.) That's 63 years. During this time I masturbated about 27 532 times. Even now I masturbate on average 1.4 times a week. Therefore, I have the exact numbers because I have out of interest a sex diary. Take a look at the link, I'm Mr.Z.
