My ex and I used to have sex multiple times a day. Eventually there came a day that we had had sex 4 times within 2 hours, when she wanted to go for round 5 it just wasnt there, i couldn't get an erection. She got mad at me and said I made her feel ugly because I couldn't get it up. From that point on our sex life took a drastic turn because I was so paranoid about hurting her feelings I would struggle to get an erection. She continued to blame me for it and come to find out she was cheating on me with her ex anyway. Good riddance to her, Haven't had an erection problem since. I didnt feel self conscious about it as much as I felt bad for making her feel ugly about her self, although looking back, she should have been enough of an adult to understand and not put that kind of pressure on a person.
