In my books it’s a cheating behavior. Do you really think blatant sexual flirting with a woman is ok? Asking for her pictures? Talking about her behind being great?

Plus how do you know if he is having sex or not? He is good at lying. Last time he was in hotel having sex for weeks lying he is out of town. How do you know he isn’t still doing the same thing? He like does. Just maybe not being gone for weeks. He isn’t stupid but he thinks you are hence he comes up with goofy explanations

I hope you test for STD and refrain from unprotected sex with him
