Hi, I m 26y.o. and for the past 8 years my erections haven t been as frequent or hard as they used to be, I got hit pretty hard with a basketball in my right testicle about 8 years ago, the pain ceased after a few hours, could that be related? Also, when having sex and about to have sex with my then girlfriend I would sometimes lose my erection. She gave me a hard time over it and I m wondering now if its psychological? I m strong and seem to be healthy. I think I have a small hernia in my groin area, would that play any role in my problems? Thanks in advance.
