What Is This Feeling?

My wife and I are new to this game. And that’s what it is for us is a game. But from the very first second i put on my device something happened? It feed something deep inside. I have read others posts and they have mentioned the same kind of thing. But what is it? And it’s not just in me. My wife has something that happens to her as well. I’m not by any means a sub. Never have been. But it’s like criponight! I miss it when it’s not on. I have always been a little kinked. And we have a better than average sex life. And I don’t have any reason to take care of myself because my wife does a great job of keeping up with my drive. So we were not looking to get into chastity at all. Never even thought of it. I was on the web looking for toys when my wife spotted a cage and said she liked the look. So I ordered one. And now really? what the hell has happened to me? Can any of you discribed what “it” is? Thanks.
