This must feel so bad to find out and someone suggested that you should ask how she’d feel if you had a mold of your exes vagina that was your go-to when she’s not around… i un-ironically think you should. just say it in a kind tone if you genuinely want her to realize how shitty this has to be for you.

If I was in your shoes, I’d never be able to reconcile the relationship. It’s worse than having a one night stand. It’s hard to argue that she likes having sex with you more than she did her ex, especially given what she has told you about preferring clitoral stimulation. No one deserves to feel like they’re second best in their own relationship.
