Jealous of my bf

I am so jealous of my boyfriend. We've been dating for almost a year and a half and we live together. And he never uses shampoo, deodorant or cologne. We shower together quite frequently and the only thing he uses is a bar of soap to clean his body. He says he hasn't used shampoo for years and years! I go through a lot of shampoo and hair product because I have super curly, thick, long hair and it gets expensive! So when we're in the shower I have this routine of shampoo, conditioner, body wash/shave and face wash and all he has to do is grab his little bar of soap and boom he's done. He has perfect hair and skin 😩 and he doesn't smell, like no body odor at all, and he sweats sometimes and still no body odor. Like I said, I'm jealous of it lol!
