I need advice.

So I am a very open minded, very sexual person. Hubby has always been more tame than I have been. That being said, today I used his eBay login to order something because I couldn’t remember my password. He knew I was using it. After I placed my order, I went to the recently viewed items list because I was going to choose to “watch” another item I had looked at. Well, I saw this in his recently viewed items.

I’m not sure what to think of it. I want to ask him about it but I literally have no idea how to bring this up. I do not in any way want to “kink shame” him if it’s something he’s genuinely interested in. I just want to know. Help me!!!!
