AITA For only staying with my husband for the money?

Me (23m) and my husband (42m) have been married for two years. Over this time frame I have discovered that I am not attracted to him and that we have an awful compatibility. He doesn't seem to mind the fact that we aren't compatible so I don't push it because I don't have a job and he makes all the money. The issue comes in when I go out to the club or local bars. I keep flirting with other men. I haven't slept with any yet, but I probably will soon. I don't want to leave my husband because of the allowance he gives me, but I feel kinda bad for wanting to have sex with other men. So AITH for wanting to sleep with other men other than my husband?
