WIBTAH If I told my wife I don’t like her mustache?

I 30M need advice with my 31F wife. We have been married for 3 years. All while we were dating this wasn’t an issue. Over the last year or so she has just let her facial hair grow out. At first she was bleaching it so that it was harder to see. But now she just lets it be and while it’s not a full on bushy mustache like a man it’s still very apparent.

This is not due to medication or depression/not taking care of herself. She works out and keeps herself well otherwise.

I’m at the point where I just can’t stand kissing her and I get extremely turned off when I see it or feel it when we do kiss.

I do not know how to bring it up without really hurting her feelings. She has a few relatives that also let theirs just grow out and don’t do anything and it makes me think of them whom I find extremely unattractive…

I’m stuck, I love her but this is really an issue for me that I can’t get over. Any advice? AITAH?

EDIT: Hey all it seems that this may be related to something medical that I didn’t realize. Going to bring that up to her to see if she can get some help with that or find out if it is PCOS before I bring up anything to do with the facial hair. Want to make sure she is ok first.

Not trying to body shame her as I understand women have body hair obviously just wanted to see if there was a way to bring it up as it’s just a preference on my end that I don’t prefer it.
