I haven't seen a thread on this subject, and it's a question I've been thinking a lot about.

How many people restrict BDSM activities to the bedroom (or wherever they have sex), and how many keep playing the roles whenever they're with their partner? Is either way more common than the other?

I ask because, though I've never had a partner, I'm sure I would only enjoy that kind of relationship within the confines of sexual activity; if my boyfriend started ordering me around in any other context, I would be offended.

So, which do you prefer? What would you say are the pros and cons of each lifestyle?
