A detailed medical and sexual history +/- physical exam are required. Give example: if you are masturbating with extreme frequency it can affect the erectile capacity or if you are not masturbating but lack of interest in your sexual partner may have the same effect. In general, erectile dysfunction due to physical condition is relatively rare at your age. See a urologist if you are too concerned.
