[36M], [37F]. Different Libidos in an otherwise fantastic marriage. Any advice for hubby?

I have repeatedly had the conversation with her about me feeling she is not physically attracted to me as I believe that must be the issue. She gets really annoyed with me and is determined that this isn't the case whatsoever and gets mad for telling her how she feels when it is apparently incorrect. But I'm not stupid, I know she's not exactly going to turn round and admit she isn't attracted to me.

She often says it's not that she isn't overly interested in sex with me, it's that she's not overly interested in sex full stop. But I can't wrap my head around that comment, because it's me she is with so the problem is that she doesn't want to have sex with me. But she says I should use this as comfort because atleast if I know she isn't a very sexually interested person, I can feel more comfortable that she wouldn't have an affair or anything like that.
