Hmm,i'll tell you! but first,answer this honestly...can you imagine yourself doing that? i mean..would you stand for someone ....eh sorry to say that "would you stand nude in front of people to draw you or to stare at you telling yourself it's okay it's an art?!
As I said earlier, I've modeled for a nude art class once. I only regretted it because it was my first time, and that's always scary. But honestly, everyone in a nude art class is a person of artistic and passionate taste and I can assure you they took me with the utmost respect!
