From random musings on another thread that I resurrected as a new one!

So I'm in the process of getting my erotica out into the world, but given the...sensitive nature of the subject matter. I'm wary of putting my real name on the tin. A pen-name sounds like an obvious solution, but not all of my erotica is in the same genre or style, and I would hate for potential readers to be disappointed or mislead.

So what do you think - one pen-name to rule them all, or different pen-names for different genres? How do you guys (and girls) go about this? What are your own experiences?
