After years of experience and my medical traing, I believe "UP" is the only way to go, as I have explained before.
However, very recently a fellow dancer gave me another reason to conclude "UP" is best: He said that when he wore the penis down, the shaft pressed against the testicles and would force them to slip out of the pouch of the dancebelt. He did a grande plie and the testicles shifted out, then were painfully pressed upon by the edges of the pouch when he rose out of plie. OUCH!
As most dancebelt pouches are very shallow, I can see this happening. Yet another reason for "UP."
