Husband doesn’t like oral

So my husband is sex-crazy and has talked to me about his fantasies and past sex life.. he claims he has never gone down on anyone and said it grosses him out. I don’t know if I entirely believe him, I have a feeling he’s tried it before at least once and maybe had a bad experience where it smelled or tasted bad or something like that.. and that would make sense to me if that was the case I’d understand why he wouldn’t want to do it again.

I know the idea turns him on because he has told me about fantasies where he would love to see another girl go down on me (he’s too jealous to imagine a guy lol), especially for the fact that he knows I would orgasm so hard from it, not because its girl on girl.

Another thing is this... a little TMI maybe, but I know he has a preference on the way it looks down there. He prefers the type with smaller hidden inner labia and kinda puffy outer labia if you know what I’m talking about... a fat pussy basically. Mine isn’t really fat and my inner labia are kinda longer and protruding unlike the type he likes, but that being said he always tells me he loves my pussy and has no problem with it at all, even when I tell him “I know it’s not your preference”. So that’s another reason why I feel like he wouldn’t want to try to go down on me because I feel like he doesn’t like the “extra skin” and might get grossed out.

Honestly speaking, if I were to go down on a girl I would have the same points I mentioned in mind, I don’t feel like I’d go down on just any pussy. But I find it hard when I think am I going to live the rest of my life without him eating me out or even just putting his tongue down there?

Anyone been through this and successfully got your SO to go down? Do you have any tips on how I can convince him?
