Well, you could argue that I am prostituting myself online right now.
I could, but I wouldn't. Since you are not making yourself naked in front of me, and I didn't ask for it.
To my question if you'd want your madam/sister/daughter to sell porn, whether off- or online, I take no answer for a "no". Except you beg to differ ;)
I thought it was a rhetorical question. Of course, I wouldn't want any family member feeling like they need to make porn or prostitute themselves for a living. But if they so choose, and they're adults making conscious choices, then it's simply none of my business.
