Going down unda

So my S.O. Refuses to go down on me, even though I am always enthusiastic to give him head. I know for a fact I don't smell, I wax, and I'm super clean, shower every day, sometimes 2x a day. I've had boyfriends go down on me before, it's never been an issue. His reasoning is "I just don't like it." Any way to get him more enthusiastic about it? I mean, it's something I guess I could go without... But damn. Lol
