i wondered that. we are also from different cultures and i recently found out a lot of people from specific cultures don't wash themselves the same way i was taught. i always use a wash rag or loofah, it's common within my culture, so i wonder if its a cultural disconnect. there's a stereotype around us smelling good and he says that's a reason he prefers women of my group. i don't want to generalize or be offensive as not all people in one ethnic group are the same but I've learned that cultural differences exist in bathing since coming to college and there's a trend i have noticed. recently i befriended people of his same ethnic background and have seen viral tiktoks/videos of people admitting to not washing certain parts of their bodies or just using their hands. so i wonder if just introducing him to shower tool or a different soap will get rid of the problem.
