Hey man, I have put together one of the wenches. I've followed the instructions "to the T" and am having a problem. I cannot seem to get it tight enough...not even close to keep it from pulling over my glans. The wench itself is not coming off...but, there is not enough pressure on the penis to make it "seat" behind the glans. Do you think I need to pick up a clamp? Dunno how much more protusion under clothing the clamp would add though.
