I don't really keep track, but pretty much every morning before I roll out of bed and go to work and most nights before going to sleep if my wife and I don't get something going instead. 8-12 times a week, I guess. It sounds like a lot but it doesn't really feel like a lot, if you know what I mean.
I am 45 years old and I have been masturbating since I was 12. I usually masturbate twice a day. I love the feeling of being naked stroking my hard cock
