May I suggest these post menopausal women have nothing to worry about and young women just keep their legs shut.

...young women just keep their legs shut.

Or at least educate themselves because sex "education"
isn't doing a very good job.
I'm a man and can find this information.

Having sex without a condom or another barrier method during your period decreases your probability of pregnancy. But it isn’t a guarantee.
Tracking ovulation and determining your fertile window can decrease your chance of getting pregnant each month.

At least do harm reduction.
