The choices are endless. And it depends on how 'demeaning' you want to get, and / or how prissy you want to make it.
"Frilly / prissy" girls names to me, are like;
Tiffany, Dimity, Chloe, Prudence, Becky, April....I could go on forever. (Not saying I don't like some of those names either!)
Also, how is he going to be dressed up? "Baby" in front of those names would suit, ie; "Baby April" if he's a bit of a sissy.
Or, if he's a slutty whore (well, he is anyway!), I'd be thinking of the traditional slutty names (Disclaimer apology here if these are dear to anyone's heart!)
Like Slut Tanya, Holly the greedy whore...you get my drift.
I think it might be a cultural thing too. There are definitely names that to me remind me of slutty chicks in Australia, but those names might not be as common or translate there. At school, there was always a slut called Debbie, Sharon, Sue, Tanya or Kylie. Apologies again if these names are dear to anyone.
