Hi Max, Good one, my wife is over 65, and we still do it, so if you women has been active in sex then things should be OK
We did have a post from a women who had a ring in side her that was preventing penetration when her man was half way in, and was looking for help, and I think that was because she had a lay off from active sex, cant think of anything else.
But its like Annie has said, if we dont use it, we lose it, so thats like most things.
Hope this helps.
Good Luck
Oh, my typo. I meant "if you don't use it, you lose it."
I think it is one of those things that "if you don't lose it, you lose it" so if someone wants to have sex after 65, she should keep having it from 50 on. The vaginal walls get thinner, also, so be sure to use lube.
