Next, I had a surprise when a male friend, whom I've never been naked with before, agreed to participate because the idea of posing was uncomfortable enough that he wanted to take on the challenge. Being a particularly brave individual, he also volunteered to reverse roles and be the artist, even though he isn't into drawing at all and hasn't sketched since art class as a kid. (One surprise I found was that for many people, it is less embarrassing to pose nude than to try and draw when you feel like you're not good at it.) As the model, he found that it was a bit awkward for a few minutes, but then quickly became pretty normal. We worked together to pick out some athletic poses, with a frisbee in place of the classical discus. This meant that his short poses were probably more physically challenging than most of the others, and he was surprised at how hard it was to hold the positions. When we switched roles, I tried to pick pretty relaxed poses, but also had shaking muscles by the end. We talked about self-consciousness, and the dilemma that heterosexual men face when they want to look at a woman but not act creepy, and how there is a social asymmetry that plays out in these situations. (For example, if a man is naked in public, there is often a perception that he is being threatening. If a woman is naked in public, that is not the usual interpretation.) I was impressed that although he doesn't draw, he was able to make sketches that were just fine. I was slightly amused at what seemed to be an exaggeration of my secondary sexual characteristics. Apparently, some things make more of an impression on heterosexual men, and that causes a bit of an optical illusion.
