Nice try with the Peter Pan link but I didn't bite.
I will try not to be vulgar hear but menopause is when the "thing that starts with V" closes up. That makes sex impossible. If you are talking about other forms of sex, they are technically known as sodomy, not sex. You can do that all day long with an 84 year old but it will not result in pregnancy. It will result in bad dreams for the rest of your life but if that's your thing then whatever.
