What does it mean for boys to buy menstrual towels for girls?

He bought her a menstrual towel to show his concern and love for her. It is also a manifestation of men's sensibility. Even some men will say to women: I want to be your menstrual towel. This is really a little abnormal sensibility. At the same time, it still implies that he will accompany her anyway and is willing to accept her bad side. At least they are boyfriend and girlfriend.
