That's not hair in the drawing (and I don't think it's a penis either, I think it's a line and it looks like it might be extending up from the fish rather than down from the figure). The part that you interpret as hair is a rough spot in the parchment that picked up more pigment. Since I have painted on vellum (and most other materials), I know what it looks like when the paint pools against rough edges.
