BDSM Bondage 

Bondage is perhaps the most accessible part of BDSM, since everyone pretty much gets how to do it. But keep in mind it also has a pretty huge learning curve. You need to be careful when restricting movement so that you don't cause injury. You'd be surprised how far experts can take it!

You might see one partner in handcuffs, hogtied and strapped to an examination table. Or perhaps hung in a swing. The Top may use a straightjacket, a chastity belt, or even a spreader (St. Andrew's Cross). The restrictions are usually part of both foreplay and fucking, although in extreme scenes the orgasms might be caused by sex toys or other devices.

If you are more the vanilla type, you might play around with scarves, shawls, tights or belts to spice things up just a tad.
