Throughout the last few years I have dealt with loss of erection right before I penetrate the woman I was with. We would kiss, caress, oral, etc, However, right when I knew it was time for me to make my move I would start to lose my erection. Especially if it took a little struggle to get it inside of her. If I managed to penetrate it would usually die down pretty quick. I have also dealt with the issue of not being able to get an erection while initiating sex. I want to know is this a result of watching too much porn? Is this a case of PIED?
