Look guys, the fact is if you are going to lose your hair its going to happen no matter if you jerk off a lot, or pump iron, or smoke weed, etc. etc! There are NO CURES, only a handful of drugs that MIGHT slow down the process. But in the end you WILL lose it unless hair cloning becomes a reality (and is affordable).
I've gone through these same thoughts over and over... I started losing my hair at 18 and its been a slow but steady process ever since. For a while it devastated my self esteem and confidence, but I've learned not to let it get me down anymore. I just accept it. Change is innevitable and no matter what anyone says there are plenty of women out there who like bald guys. The thing that will turn a woman off is a wussy guy who can't accept reality. Think about it, its the difference between George Costanza from Seinfeld and Vin Deisel.
So fvck it, lift if you want, jerk it if you want... just get on with life.
