I'm not sure you can really drag someone into BDSM.

My personal theory is that bdsm is a lot like mathematics, in that either you have the kind of brain that just grasps it and says 'yes' or that you don't. Now admittedly, it takes education in either case to make the most of your talent, and some people that are wired for kink would never recognise it until they tried it, so maybe that's the case.

But as has been said, communication and starting small are really the ways to go here.
