My wife had an affair, but we are trying to work things out but I can t get an erection without taking a dietary supplement pill that s bought over the counter. Now they aren t working, a couple times it was really good and we enjoyed each other, but I keep thinking about him being with her and can t get anything going. My wife is beautiful, but I feel useless and not like a man. I went to ED doctor and he gave me testosterone gel, said my level was just over 300 which was in the normal range. I don t know if my problem is physical or mental. I m getting really frustrated trying to figure out whats wrong with me. Can you please help me?
