Not sure what to do

So my husband and I have been together since high school. We were each other's first everything. Last night we got a little drunk and he took us to this shady place with private rooms. We were in a room doing our thing when I realized there was a hole in the wall and someone was on the other side rubbing one out watching us. I lost my shit and insisted on leaving, but now I'm all stuck in my head because my husband seemed totally fine and like he knew about all if it. I keep feeling like I'm not enough and he needs some crazy kinky shit to get off on now. I'm so upset and I don't exactly know why or what to do. 😭
