We have been married for 8 years. I have given him oral sex just once in all that time. I loved doing this for him but he told me he didn’t like it. He said he was not clean. He has never given me oral, not once. Two weeks ago, I found out he has been sleeping with someone else. This woman texted me to say she had been sleeping with him and that their sex was great, so I would think they have been doing oral sex. What do you think I should do?
