Ask your girlfriend what she likes about it and write down a list on what she'll be willing to do. Talk to her and listen to her carefullly, there's on forms of bondage, she might like it rough and than there's light bondage which I'm into cause I personally don't like whips or anything. If anything I prefer paddles over whips anyday and ask her how rough is too rough. What are you're turns offs? It's best to ask these kinds of questions before you get started. Than the fun part is to go shopping, sometimes they'll say bondage kits which sells everything together. Tie her up and use toys on her until she's getting ready to have an orgasmn and than stop out of nowhere; than ask her to beg for you to use the toy on her again. Using toys is a great way to tease. You could also use ice, that's another great way. Everyone is different, just remember to talk to her and ask her what's she's willing to try and what wouldn't work for her. Have fun and remember be safe!
