eating me out first time advice

so my boyfriend wants to eat me out, and I want him to too, but I’m just insecure and I don’t know if i’ll be able to relax. I take care of myself down there and shave to the best of my ability, but I’m definitely not bald down there and do have some hair. he knows that. also, it doesn’t smell like roses down there. I wash and clean it and don’t have any STDs or infections lol but it just naturally doesn’t smell beautiful you know???? how can I just relax and get past it?
