Dear service user, Thanks for writing to HCM. I can understand your concern about loss of erection before vaginal ejaculation and also for having child. Loss of established erection is commonly caused by performance anxiety. Occasional failure can occur to almost every man in his life. When this happens, one gets concerned about performance during next sexual encounter. He thinks whether he would be able to satisfy the partner or not. So, his mind thinks mostly about quality of erection and performance. For constant erection continuous exciting/romantic/erotic feelings should be there in mind. If mind is diverted to concern about erection (being scared in your case), you will lose erection. This in turn reduces your confidence and it again affects the erection. Having erection during masturbation indicates that your organs are functioning absolutely normally. Masturbation is a healthy part of sexual activity and it does not cause impotency or infertility. There are effective behavior therapies having strong research evidence for psychogenic erectile dysfunction. You can read about sensate focus on internet. I suggest having consultation with psychiatrist. There are medications like verdalafil or tadalafil which can be helpful with behavior therapy. It is good to listen that your semen analysis report is normal. As far as pregnancy is concerned, you may consult infertility specialist for same. There are treatment options like artificial insemination which can be useful for you. Wish you good health.
