Not really...depends where you go in Canada. Personally the girls in Montreal are amazing by far...Still, I would choose a Russian girl over a Canadian girl anyday.
Yeah it's starting to get annoying...and to the OP, you're a fucking hypocrite. You say you don't care if a performer does IR but you mentioned that you admire adult stars who don't shoot IR scenes. So obviously you have a problem when a girl decides to work with blacks. Eat a dick!
Just work in the porn industry and find out for yourself or write a letter to an adult film star or an OCSM and find out what they have to say. Stop wasting your time by being an attention seeking troll on these boards. If you want a REAL answer, I suggest (once again) you talk to an adult film...
