I never play favourites, especially with creative spaces.
I was engulfed in art and learning about art history and the different ways of making art and at that time I was also an art student and I was experimenting a lot and trying a lot of different things.
But the majority of it, above all, will be painting with my penis in many forms.
Doing that helps relubricate the tip and lubricate the paint so it glides on a bit better.
