Many guys end up finishing their masturbating after a few minutes. Some go 30-45 minutes. Some over an hour. Some three hours.
It all really depends on if you keep stroking away without stopping. I find it very easy to last as long as I want if I take my hand off my cock every few minutes. I switch the positioning of my hand and how I am stroking and such.
Over the years, I have slowly conditioned myself to where I can masturbate for as long as I want without ending until I want to.
Do you have this kind of control? Are you able to do this? I'm wondering how rare or common this is?
