Even if it is told here, a small introduction: I met him because he was friend of my sister, he is a bit older than me, so the belt was not a surprise for him.
Now, answering your question, it had two clearly identified periods.
Firstly de belt was the elephant around the table, in fact not only the belt but everything with a more sexual nature. It was great because it give a stable and calm environment to the relationship.
But later, this frame became to narrow. It was related with my crise two years ago, yes, all was calm but it was avoiding I could reach a fulfill or even a maturation.
Transition was not easy at all, not only for the belt, but basically was a transition of a friend relationship to a true crush relationship, and then we started to talk openly.
At the end, I can say he is delighted with the topic and even we make plans. He asks a lot about belt usage and I have to ask him a lot about expected wifely behavior.
I hope I answered you.
