I had a circumcision last of April, I am 64 years old, had semi erections while walking around for a few months, now that I have a new girl friend, since June, we have been having sex since July, but I never climax, or ejakulate, I dont even get to the point of sexual spasms? I enjoy sex with her although I am unable to maintain an erection with out taking half of a viagara. Is inability to ejakulate someting to worry about, or a side effect of circumcison? girl friend wonders If I am just to psychologically blocked? My wife of 41 years died 2 years ago??
