Now I’m worried....

Some of you may have seen my post last night about my husband pretty much being in-interested in me sexually. Well, we argued over it and had fabulous sex before bed last night. I can’t help but worry if you ladies may be right though. What if he is cheating and I just don’t know and he’s covering his tracks well. Or what if he is a closeted gay man and I’m his cover? Idk if I’m just being paranoid or if one of them is actually true. How would I go about finding out if they are true or not because I know for a fact he will just get pissed off if I try to talk to him about it. He thinks it’s me accusing him. I don’t want to make him mad, but I just feel like maybe something is off.....
