Have you asked her if she would care? I wouldn’t care if my husband was out getting it on the side. It would be a relief, to be honest. It would be even more of a relief if he was ok with me getting it on the side but one can only dream on that front.That's what really irritates me. I feel like asking, "Why does that bother you? It's not like they're getting something you even want."
The way I look at this is that she has abandoned this side of our marriage. By abandoning the physical intimacy side of the marriage, she surrendered any right to determine - or even be part of - MY sex life. So while I'm not out there hunting for it, I have zero guilt about taking care of MY sexual needs.
