Sup /p/

I will be shooting a topless model next week. Any suggestions?

This will be the first for me. How do I not get a boner? The model is bretty much 10/10 and I dont want to look like a total jerk and give that "rapey-rapey" feeling, look all professional, but i'm very nervous and, what if the woody will be visible?

Any suggestions welcome. I really want to work it out between her and me on a professional side cause if the shots will be nice and shes all happy we might do more and more shoots afterwards.

btw we'll be shooting outside
