Husband used a dildo!?

So my husband admitted to using a dildo while I was gone. He purchased one and even used mine when I was gone. He liked it. I’m not opposed to it, for I’ve got

Some kinks myself. However, I asked if maybe he’d be into a dude and he had no clue because he has never tried. Is this concerning to me? He’s open to swinging. To even try me and another guy out. I’m not sure how I feel about sharing him but I feel I’m pretty open. Maybe just jealous. We have kids and have been starting new things in the bedroom. I’m not entirely sure how to approach this. I offered him a blowie and brought my dildo to use also but he wasn’t feeling it. Thought it could be fun and would get to know his limits. Any suggestions? Maybe he’s no? Or maybe he just likes how it feels. He doesn’t seem to have any clue. I’m pretty open. No sharing with women yet though. Not into that. 😅😅😅😅
