Leviticus 15:20

18 If a man lies with a woman and there is an emission of semen, both must bathe with water, and they will remain unclean until evening.

19 When a woman has a discharge consisting of blood from her body, she will be unclean due to her menstruation for seven days, and anyone who touches her will be unclean until evening.

Anything on which she lies or sits during her menstruation will be unclean,

21 and anyone who touches her bed must wash his clothes and bathe with water, and he will be unclean until evening.

22 Whoever touches any furniture on which she was sitting must wash his clothes and bathe with water, and he will be unclean until evening.

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
