I am 61, my sex life has been good. lately, when i have intercourse with my wife, i was not as hard as i use to be? is there something wrong?

Erection troubles: Given your age i would advise a good and thorough evaluation with a men's health expert. You could have a number of reasons for this problem. But, you also do not need to suffer in silence. There is a chance you have thyroid or testosterone abnormalities. You may have arterial damage from high blood pressure. There are medications that can also work to help you enjoy a full sex life.
