No kidding. A lot of people have sex and p**rn addiction problems. 5 hours is actually nothing, I've edged for 36 hours straight before.
It's not all about AR sensitivity. I am not at all "allergic" to androgens. Based on my AR sensitivity I should never go bald, yet I almost went completely bald. DHT is produced to maintain an erection, and scientific studies back this up. There have been no scientific studies on masturbation and baldness, but there have been studies on hormones and masturbation that show DHT does increase. 5 hours a week of maintaining an erection isn't going to make you go bald, but 5 hours every day is producing a tremendous amount of extra DHT.
