most of the girls are not that naive. some are clean and state it very clearly "no hanky panky". some girls are more open minded and say "let see how things goes". some will do anything for the "right price". some will pretend to be so sweet and innocent and at the end of the shoot, she says "i'm starting to feel horny"

from experience. around 30-40% will be completely clean (no touching). 10-20% will do for the right price. The remainder will do it (for free) with the right condition and environment
