I remember my father told me once that at a certain age sex will eventually end, he was talking old age of course. That got me to thinking, if there was a certain age where sex just doesn't happen any more for people (including married couples). Can you imagine yourself being done with it by a certain age? I'm not seeing life at all past 80, but I'm probably being cute by throwing that number out.

Well, it doesn't stop at 66.

Hell, there are still women in their 70s who are sexually active AND getting pregnant, though the two may not be related, I don't know...I think some people just have it and others don't...they say guys peak at 17 and women at 33, I don't know if it's true or not but clearly peaking doesn't mean dead and buried afterwards, whereas some people can lose it early on and it stays gone. I think it just depends on the person.

No. You can have sex as long as you're able to, I guess. They don't make Viagra for nothing.
