A book that serves as an introduction to relationships

I’m a 20-something year old who’s never been in a relationship and I’m kind of intimidated by the idea of one, but I would like to start getting into the dating world. Which is why I’d like to read a non-fiction book that can give me some sort of perspective on relationships and dating since I’ve missed out on years of experience, as dumb as it sounds the idea of a relationship feels foreign to me
