Last few weeks my wife has been quite distant and consumed in her phone. Our sex life has always been good but recently quietened down.

Suspicious I did something I thought I'd never do and I snooped through her phone after she fell asleep. Once in I found many messages and picture exchanges from an unknown number. At first I felt betrayed and angry but after reading through I found myself getting more and more turned on.

The messages all started early December around the time she spent the night out with a work Xmas party. She said at the time she stayed at her work girlfriend's house the night but after seeing this I am now thinking it wasn't a work girlfriend.

The texts started off quite flirty and but gradually progressed to sexting and eventually nude exchanges, one short clip included him stroking himself to finish and mentioning how he wished it was her mouth "again". This clip has made me so hard on numerous occasions. He is very obviously bigger than me as well and hearing my wife talk about how big he is only further heightens the arousal.

The thought of my wife with another man is not something I thought I'd like but now it appears I can't stop thinking about it. For now I've decided to not confront her and instead keep snooping and enjoy the nightly reading material. Is this wrong?

UPDATE 11/01 - Although the messages never really spelt out she was cheating at the time of the he last post their recent msg exchange there is no doubt. One message said that "he was the best fuck she's ever had" which confirms my already accepted fears. As I find this a turn on I don't want it to stop, I know I will need to confront her bout this at some stage, but where do we go from here? Back to our boring sex life or consider Non-monogamy or cuck or hotwife etc.... ??? I have thinking to do.
