ernest,

I've been meaning to ask you, we're told not to use a constriction ring
for more than 30 minutes. Apparently, they cause zero flow of blood
through the veins and out of the penis. Again apparently, this could
cause damage to the penis.

If an injectable,especially tri-mix, is used and a 3-4 hour erection
ensues, is that the same as using a constriction ring? Or does tri-mix
allow a little venous leakage just as a natural erection would?
