A lot of times when you have a kink and you act upon it you can feel shame about it afterwards. Someone may feel disappointed because it wasn’t what they thought or because they did or didn’t do something and regret it. There’s lots of factors that could play into this. I think the two of you could give it some time, and then talk about what you or what he would have liked to do differently, or whether or not he would do it again at all. Maybe it would’ve been better for him had be been involved, maybe he was fine with everything but there was one small thing about it that he would have rather not seen. But right now he’s feeling a lot of things at once so it may need some time before this conversation can be had. Kudos to you, truly, for what you’ve done here. You’ve done nothing wrong and I can’t think of a better way of going about this than the way you did. It’s just like everyone else is saying, the way a fantasy is when it’s still in your head can be a lot different than the way it is when it becomes real
