Thought I needed to update his ref sheet.
Regrettably, I have also taken the liberty of making a NSFW version of this ref. Now, when you go to the link below, please do know I haven't drawn anywhere even close to a professional dick since my days of drawing dicks on the whiteboard in high school. Also, this is obviously some 18+ territory, so only proceed if you are of age.
