I had operated hernia repair surgery in july 2016. Right now I am fit and fine. I am 26 year unmarried boy and planning for marriage. But from operation onwards my mind gets distracted means I am feel that I will not enjoyed normal sex life after marriage. Normally in morning my penis get erected fully but if I see something or sometimes it not get fully erect or if erect then not remain constant after fraction of minutes because of fear abt sex. please help me to remove distraction.
