Bored with husband

I mean not really, I LOVE him to pieces and the sex isn’t bad... but he’s the only one I’ve been with. And I have no doubts I want to spend the rest of my life with him. But, lately I’ve had a wandering eye and I find myself being very flirty with other men. It comes from an entirely lusty place and I dont have “feelings” for any of them. What can I do? Ive only had sex with my husband but he on the other hand had several other partners before me. I can’t take the guilt of feeling like this at all. I don’t think I’d ever cheat but I’d be lying if I didn’t say I feel curious at times.
