You know that if I put everything you asked in this game, some people may start taking their own lives, right?..
But seriously:
1) First, I'm glad you got the jokes - not everyone here does, apparently...
2) There is already a "Slut" stat (really), which influences in many subtle ways. So, no need for a whore, which is different.
And I
really like Slutty Paula.
Many others, especially outside the house, are already extreme sluts to begin with - and one of the things you should do in "Saving Paula" is to, well, save Paula from them.
There are more virtuous girls, like Jenny and Zoe, but they are over 18, study performance arts, and are extremely hot.
So, virginity is hard to find in this game, just saying...

3) She isn't a whore, so she will not take money for sex. But she may get corrupted into
a lot of shit by her producers and others. It's your job in the game to save her from that, but you may
choose not to.
The point of the game is helping Paula - and Jessica - avoid those people. But again, it's a
choice.
4) I really should start watching the movies
you're watching...
