Question is, why such a small prosthetic? I haven't seen the movie or know the name of it. Can someone please give me the name? I went to IMDB but there is a whole slew of movies and TV shows he's been in and knowing they would not have THAT picture posted there, I would not be able to find it that way.
You're thinking of Wolf Girl (a.k.a. Blood Moon) about a girl with hypertrichosis (i.e., excessive hair on her face and body).

I believe Shawn's character in the movie is supposed to be suffering from Pinner syndrome (i.e., an unusually small penis, a.k.a. a "micropenis). The relevance to the plot is that at first you're supposed to think that he's "normal" (as compared to Wolf Girl) until he drops the towel and you find out that he's also a "freak."

Here's the pic you wanted.

I'm sure Shawn's micropenis was a special effect of some kind, as in some of his other movies you can see that he has a perfectly reasonable bulge. Check out the pic I posted here:
