Too much masturbation = low sex drive?
I am 25 and sometimes I have trouble getting an erection with my girlfriend of 3 months. At first I thought I had ED but when I'm by myself, I have no problem "getting hard". When I'm with her, most of the time I have trouble "getting hard". Most of the time I use Cialis or Viagra to get hard so she doesn't get frustrated. I was wondering if too much masturbation leads to low sex drive AND inability to get an erection?
