Husband is too embarrassed to tell me what he wants

So to be honest i saw a post on my main about the same thing the other day that inspired me to write this.

My husband and I have a very great marriage. We have beautiful kids and I love him very deeply.

So a while ago when we first got married I found out he had a rather interesting fetish. He was in the shower and I had to go #2 and he kept like watching me and then he got "aroused"

I asked him later about it and he looked away and kept denying it but then I asked if he liked to see that and he just nodded. He almost cried he was so embarrassed I felt horrible so I just let it be. Throughout the years similar things have happened, but he got a promotion at work and I figure now would be a good time to "reward" him with something.

Every time I ask him about it he feels humiliated. So I told him "we don't have to talk about It but one of these nights if I suprised you with something involving my (ya know) would you like that?"

And his eyes kinda widened and he just nodded. I still even then felt bad for bringing it up he was so embarrassed.

I guess I'm asking for ideas. Gals, How would you involve that kind of thing in the bedroom for the first time? Any safety precautions to keep in mind? Any sex acts to suprise him with would be greatly appreciated.

Go ahead and bully me all you want I guess, this is a throwaway account.

Would like to add, due to the harassment I've gotten (already) ladies only please.
