Dear sir, Last year in march 2014 I lost my erection during penetration for one or two times. But then I got recovered and had successful sex with my girlfriend. But somehow this has remained in my mind. June 2014 I broke up with my girlfriend and it's been more than 1 year I am not in physical contact with anyone. In last 1 year I have seen lost interest in sex, weak erection while menstruation, no more getting excited sexually easily. I do get morning erection but it is not as hard as it used to before. I get excited by watching porn and get enough erection for penetration but it is not rock hard like before. I cannot judge till I have sex but soon I am getting married and I am not sure I will get erection or not. Is this a performance anxiety or some physical problem? Is erectile dysfunction treatable?
