I masturbate sometimes 4-5 times in a week and sometimes 2-3 times in a week when I talk to my fiance on phone I wanted to have with with her that's why I masturbate but I am not having erection at morning while I wake up but when I masturbate my penis erect and becomes hard and sperm also releases in good quantity and I have no night fall may due to masturbation but from last few days I am tensed due to no erection at the time of morning and even I don't remember that I am having erection at the time of morning earlier also but whenever I talk to my fiance I get excited and I touch my penis and it becomes harder after 15-20 min or sometime ever after half an hour I masturbate so is there any problem as my friends get morning erection please help with proper guidance.
