I don't want to and I didn't like it when I have

Background: been with my partner for a few years now, with multiple partners previously all serious relationships.

I've been intimate with my partners prior to my current relationship, and I have always enjoyed going down on them. And to their feedback, and later on feedback from their friends, they enjoyed their time with me.

Fast forward to today, and I've been with my current partner for a few years, and we are very sexually active. I've gone down on her previously, but I didn't like it. The taste is, different. And, super shallow of me here, but, the outside appearance of her down there isn't very, attractive? Idk if that's the right word. But I think you get it? Idk.

Anyways, it's more the combination of the taste and appearance of it than any single one. She's asked me to go down on her, even trying to direct my head, however, I make my way back up without putting my mouth there.

AITH? I have never told her this and I don't think there is any nice way of breaking this news to anyone. So, do I just live with it?
