You won't find any reviews on this forum because this one is generally for the GTA.
You can go on sp411 Kitchener. You might find some info on there, or ask questions on there.
You can get cbj or FS with some girls, but you gotta have the extra cash, and It's only discussed in the room.
I have the impression that Juliette only offers FS with regular clients. Go play with her and make her feel comfortable. She may give you FS on your second or third visit. Just don't be afraid to leave a review here, even though this is a GTA forum.
