Trying new things!

Ladies I need your help with some stuff going on with my new hook up, we have been friends for years and finally decided to start getting it on bc we both don’t want relationships but we both want sex and a cuddle 😂 I am very submissive and I love all that stuff, bondage and all that I vibe for that, he likes some stuff but he really hasn’t had a lot of variation in the past and I wanna spice it up for him, see what he likes and doesn’t like. I need ideas on different things to do with him! I’m trying to be a little more dominant but I’m not doing so great, like I dong know what to do with a guy who’s handcuffed to the bed 😂 any advice would be much appreciated!
