Do you play?

I bought this yesterday.  
I have wanted my husband to take this initiative for many years (7 years) and he has no interest. He's usually not interested in sex at all. 
I told him I had bought it and hoped that our money wasn't wasted. 
We didn't use it last night, but we did have sex.
He says this is "new territory" (even though we've been married 7 years) and doesn't know what to do. (I told him to watch some videos...)
Did you have a partner that was reluctant in trying new things? Fun things. 
What does your partner do to you while you're tied up? 
I offered to restrain him first, he wasn't interested
