Early Christmas Present, need advice! (Handcuffs)

My boyfriend gave me an early Christmas present yesterday. He bought me some really sexy lingerie, furry handcuffs, and a small vibrator, a couple things I’ve been wanting to bring into our sex life for a while. I was so excited I screamed, twice 😂

We used it that same night and everything was great, until we used the handcuffs. I’ve always wanted to try it but to be honest it was kinda awkward and not nearly as pleasurable as I thought. Our sex life is A-mazing now but it was a bit awkward at first so I know it’s normal for trying new things to be a little weird and we will become more smooth with it eventually, but I was wondering if anyone had any tips on how they use their handcuffs for optimum pleasure and whatnot.
