<human>: So I got my hair cut yesterday and upon coming home my girlfriend asked me to turn my head and started looking at my hair up close. She then says, "I don't want to freak you out, but your hair is thinner back where guys get a bald spot. I think you're starting to lose your hair". We took video of my head up close so she could show me and sure enough, you can see my scalp more easily back there. This is a new development within the past year or two i guess. 

I'm 25, always considered myself decent looking, whole family has hair. Now what? Rogaine? Propecia apparently is linked to low labido. I would rather have no hair than no erection. Any others have any tips/suggestions? Thanks.
