Whips are a turn on

Some people like to be whipped. The feel of physical pain turns them on. Whether you're a sadist or a masochist, if pain turns you on then it's likely you'd make a good model for BDSM porn.

BDSM porn can involve whips, ball gags, and all kinds of toys designed to induce the maximum amount of pleasure. Some of these toys, however, tend to look more akin to torture devices than anything else. Try watching fetish porn that involves binding someone upside down and suspending them from the roof.

Or watch someone getting whipped until their ass is red and raw. Some actors actually break down into tears, but for this kind of people their pain translates into pleasure. If you're into this sort of thing, then BDSM is the way to go.
