I do not deny that I have made drawings and watercolors of an erotic nature. But they are always works of art. Are there no artists who have done erotic pictures?
Writing nonfiction is more like sculpture, a matter of shaping the research into the finished thing. Novels are like paintings, specifically watercolors. Every stroke you put down you have to go with. Of course you can rewrite, but the original strokes are still there in the texture of the thing.
It's such a human condition, whether you're a great track star or a great knitting person or you paint watercolors - someone knows who you are.
Color comes very easy to me. And watercolors have a particular tendency to stay grounded, unlike digital color. I find that digital color wants to go wild, to lose control and be as bright and loud as possible. With watercolor, it's the opposite. It's harder to get bright, vivid colors when you need them. But that's okay; I prefer it that way.
I paint daily with watercolors on 5-by-7-inch pads that are small enough for me to take them everywhere.
