Show yourself

Isn't there a theory that an artist will often include aspects of themselves in their work?
Why is it then, that when I have a brief break in the adrenaline and I have the temerity to have a doodle just for the sake of it, I will draw skinny naked guys?
Here's me, in reality making a fine job of looking like Captain Plumpy, and at a time when I could be absent mindedly revealing my true self, I do stuff like this? What's that about?
No doubt any passing psychologist could provide a rational answer.

If you know anyone, please drag them along to tell me what the deal is.
