A good scene includes elements that both of you enjoy. And that comes with communication and learning each other. I've had these discussions before a scene and even had to communicate during a scene so things could be adjusted. Communication is literally the end all be all for bdsm.
I don't know how selfish of a lover your husband is on the whole. If he isn't a selfish lover then you should be able to get him to understand the whole give and take thing when it comes to sex and fun and games - including elements in the scene that both of you enjoy. If he is a selfish lover... oysh. Then you've got to start from square one.
Again, that all goes back to communication. I know it can be difficult and even embarrassing, but it's very important to be specific when talking about bdsm. One of the things you can try is making it a special talk with some ground rules suitable to your personalities and relationship. i.e. no yelling, if feelings get hurt take a few moments time out... whatever works for you guys.
