Is it me?

Hubby and I are both bisexual. We have an amazing relationship and sex life and love to spice it up. With or without others. However, I feel like it consumes his mind now to be with another dude and it makes me super insecure. He will constantly put in butt plugs to stretch his asshole, always talks about a bi gang bang, and wants that if we do Anything he has to be fucked too. It bothers me because im like is he more into guys? What is with this obsession? I’m a bisexual woman and I can go the rest of my life not having intimate relations with a woman. Am I being exhausting? Are my feelings valid? Even wants me to use him as an escort to make us money. (We are having financial problems) I trust that he won’t do it behind my back but I hate that he always fricken wants to be fucked by a dude. Like why aren’t you happy with just me? And bringing someone in on occasions? Why do you have to talk about it? Why do you have to get it if I get it? It seems unfair but I won’t do it if you don’t want me to.
