Men often notice more distinct changes.
It may take longer to get an erection or the erection may not be as firm or as large as in earlier years. The feeling that an ejaculation is about to happen may be shorter. The loss of erection after orgasm may be more rapid or it may take longer before an erection is again possible. Some men may find they need more manual stimulation. As men get older, impotence seems to increase, especially in men with heart disease, hypertension, and diabetes.
