So how big a hazard is it you're pointing toward the doctor?

LOL
I've seen guys who are hard in the waiting room at the doctors office,
One guy in particular was very noticeable up to mid chest level, the
doctor came in to see me immediately after seeing him
and had to readjust as he entered, there was no doubt
he was physically aroused by the sight...after all we are all sexual beings,
straight, gay or bi...or somewhere on the continuum...
So How big is it? And is it obvious?
