How can I accept my mother-in-law eavesdropping on my husband's sexual intercourse with me?

It is normal. Your sex is not only the love between men and women, but also their family background. Put it down and make her proud of her son!

Or I am afraid (worried) that you are young, have too much desire, don't know how to take care of your body, and ask too much. There is no harm in it, and it is not as dirty as you think!
