I would really like to get my boyfriend into the idea of bondage but whenever I try to discuss it with him he thinks that I am kidding. Any ideas on how to approach the subject without it coming across as a joke or too serious and scaring him. Also he is very quick to judge on where I get certain ideas from because he has some jealousy issues so I need it to come across in a way that doesn't allow him to assume I am cheating with someone who does this. I am not cheating for the record I just would really like to try it.
