when post-menopausal women have sex, do they use condoms?

You might have heard of Sexually Transmitted Disease.

Yes they do if not in a monogamous relationship. Herpes sucks at any age.

Yes, I have. but i recall you're annoyed i post questions here, since it is the point of this entire forum.
i guess that's hard-line Mid-Western morals for you.

I don't know if you have any experience with herpes. Most of the time it is a one time rash. Before the pharmaceutical companies started marketing drugs in the 1970s herpes was unheard of. It was a "rash in an inconvenient place".

If you have ever had cold sores (around your mouth or around your genitals), you have herpes. Very rarely it causes problems. They don't test for it even if you ask for STD tests because it is so common and rarely cause significant problems. Sixty five percent of people have Herpes 1, and about twenty percent of people (slightly higher for women) have Herpes 2.

There are almost certainly people reading this post who have herpes and don't know it.

Now if you want to worry about a serious STD, HIV sucks.
