I was brought up in much the same environment; I believe my parents would faint if they heard of some of the things I did *g*.

For me, though, virtue is a personal thing. Calling myself a 'whore' brings no negative feelings now, only that delicious wash of humiliation. But if I were to literally BE a whore, as in solicit strangers for sex, well, that's where my personal virtue comes in. I would never do such a thing. My dom agrees with this. Other doms however certainly might prefer subs who actually would solicit strangers for sex if they were told to.

I too hope this answer is close to what you're looking for -- tough subject, that.
