I hate these threads. There is no link between masterbation and hair loss. Say it with me, there is no link between masterbation and hair loss.
If differences in male pattern baldness patterns do exist amongst 20 year olds in the 50's and 20 yr olds today (which, I also have my doubts about) it is not because they had less p**rn or lived with high morals and didn't jerk off as much/have sex until they were married in the 50's it is because they inject hormones into everything nowadays. Our food is raised/harvested and prepared differently. This could also explain why teenage Egyptians living in Egypt don't go bald as often as Americans here.
Who knows if these differences even exist. I have seen a number of users here posting from the UK, Germany, and Australia. I think we don't see as many pictures of bald guys in the 50's because balding 20 yr olds don't want to take pictures. I know I avoid the camera at all costs now. There are plenty of bald old guys, aren't there? Who knows when they really lost their hair. In 40 years, I'm not going to be telling everyone at what age I started losing my hair.
Anyway, I think we have to get over it and stop kicking ourselves over masterbating when we were kids. It's not healthy, and I think when we get down to it the urban legend of masterbation and hair loss stems from the church and parents trying to suppress their kids.
