Caught my husband using my sex toys…

I (28f) just caught my husband (29m) using my sex toy(s). Both our (shared) vibrating cock ring and my dildo.

I didn't see him physically use them, but he sets up his laptop in our shower area and then will take his toy (suctioned flesh light) and then the others. The only thing I can infer here is that he's using my toys in his ass?

Honestly, it's kinda a turn on! BUT I find it really gross that he's using the toys in his ass, then they're going into my vagina at some point. I know he's in the shower, but I got a weird UTI last month and I wonder if this is why.

How do I confront this? I really don't think he's gay or anything. I don't mind him using a toy in his ass, but I find it gross that he would use mine and not just establish his own.

UPDATE: We talked… He just seemed to shut down. I told him it was okay if he likes what he likes, but I would like to separate our toys. He said, "he just likes the simulation." I don't think thats it but doesn't want to seem to even want to express the idea. He's never this shut down. I asked him if he wanted to peg. It was a HELL NO! I just told him I'm open to anything and I love him no matter what. Wish me luck! I hope he opens up at some point!
