Cheated with escort and confessed

I confessed to my wife about cheating on her with a hooker. I told her it was oral but I also did a very brief vaginal sex. We are currently recovering from my affair and are moving forward. Should I tell her about the vaginal bit? We are in counseling and it happened a couple months ago. She told me she forgives me but I haven't told her about the vaginal bit. I'm scared she won't forgive me because she told me she could handle the oral image but she can't handle the image of her on top of me. Should I tell her that knowingly that it will undo our recovery? Everything has been going good, we are talking more, going on dates more, she is the happiest I have seen her in a long time.
