I say to each their own, if it works for both people great. But, I don't think it is for me. If FI came to me with that question it would be the absolute last resort to save my marriage. I say try couples weekends or a make-over, not new girl. (and I love how he said YOUNGER! WFT) The writer should have asked for permission with someone LONGER. heehee.
Anyway, I do understand where the question comes from. Our agreement is don't do anything you wouldn't want to other to do or couldn't forgive. I'm ok with strippers at the bachelor party because I know he is coming home to me and will marry me! I could forgive a stripper kissing him when he is drunk faster than I could if he was going out after work every night with a co-worker for drinks, even if nothing happened.
