The Effects of Aging on Sex in Men
In men, hormone levels usually go down very gradually from a peak in late teens onwards. In some men, a quicker drop in their late fifties leads to symptoms like the menopause in women. These can be hot flushes, aches and pains in joints, loss of energy, including libido, and a sense of slowing up mentally.
The sexual response in men is affected. Erections come less easily and less often. They are less hard, and once they have gone down are more difficult to get back. Orgasms are less intense and rhythmic spasms of the muscles are over quicker. The amount of semen is less and the refractory period after orgasm is longer. While the need to ejaculate is less intense, sexual satisfaction amongst older men is often said to be good. The ability to continue being sexual certainly remains an important part of the older man’s self-image..
The frequency of sexual activity goes down with age but is very varied. Men who start having sex early in life are more likely to go on till late in life. The amount of sexual activity depends on having or getting a partner. The longer a couple have been together the less sex they have. |
