The Moral Reason: The human body, when totally naked, is a remarkable design. When clothes are removed, barriers between people come down. Clothing makes a number of statements about who you are, where you have come from, your social class, your values even. It is entirely a human construct. Without clothes, we struggle to make any judgements at all about people. We all become equal.
The Aesthetic Reason: Another reason I paint, is because I enjoy the structures of muscles and bones and how they look when at peak fitness altogether in a body. The balance and poise of a dancer, the tight abdominals of an athlete.
The Desire Reason: I paint that particular body because I desire to have it myself (or look like I have it) or to touch it. So, in a somewhat goddess-like ambition, I create what I want so I can have it.
