How common is oral sex?

Tabitha • AFAB gender fluid Demi girl! Hoping for a baby WAY down the road, for now trying for a puppy!
I've had boyfriends who love doing it and some who hate it, but I sure as hell love it!
My current boyfriend of almost 6 months hates it, says he can't stand the feeling and how wet it is. (You'd think that would make him feel a little better!)
I really want him to do it more often, now it just seems like I'm forcing him when I'm happy to give him oral. I don't want to do an ultimatum because he'd be fine going without sex for months but I just want a little love back now and then!
Any advice on how to talk about it? Maybe get him more eager, any products which made me better, more fun, etc.
