Josh, how did you get so good at drawing butts and boobies?

For a while I was terrible, then I got a book on human anatomy and looked through pretty much all of it. Then if there was some particular bit of nakedness I was having trouble with, I would go to the internet and consult pictures of Susana Spears and other models.

Anyone who wants to draw porn or even mild cheesecake needs to do these two things.
