性反应-男性性反应
The Sexual Response - The Male Response

老龄男性性反应

社会上，有一些人认为性活动是年轻人的特权。确实，他们中某些人甚至不能把老年人想象成有性的生物。但是，男女都不必因为上了年纪而过早放弃了令人满意的性的关系。

婚内性交年频率    Annual frequency of marital intercourse over the years

居住在不同国家里的2个男人，在35年里仔细记载的婚内性交频率。图表说明他们50岁后逐渐减少了性行为。
Two men, living in different countries, over 35 years carefully recorded the frequency of their marital intercourse. The graphs illustrate their diminishing sexual activity after the age of 50.

减弱的而又令人愉悦的性反应
老年男性性行为频率降低，但是性反应仍保持相同。显然，老年人没有从前那样强壮，许多人反应迟缓。例如，一个60岁的男人没有他20岁的时候跑得快。但是，并不意味着他根本不能跑。确实，假若他一直有规律地跑步，可能比某些缺乏锻炼的年轻人有能力跑得更好。对于性行为也是同样的道理。在一生中一直有性活动的男性到了老年能够指望很好地延续他们的性交能力。尽管如此，老年人的性活动肯定是有所改变的。

The Sexual Response in Older Men

There are many people in our society who consider sexual activity a privilege of the young. Indeed, some of them cannot even conceive of older persons as sexual beings. However, neither men nor women have to forego satisfying sexual relationships because of advancing age.

A weaker, but still enjoyable response
In older men, the frequency of sexual activity decreases, but the sexual response remains essentially the same. Obviously, older people lose some of their former physical strength, and many of their reactions become slower. For example, a man of sixty cannot run as far and as fast as he could in his twenties. This does not mean, however, that he cannot run at all. Indeed, if he has been practicing regularly he may very well be able to jog along better than certain younger men who lack such practice. The same is true for sexual activity. Men who have been sexually active all their lives can expect to continue sexual intercourse well into old age. Still, certain minor changes have to be expected.
