What do you guys think of this site with the Mushroom Head Cylinder.
Looks interesting.. Expensive though... They also have smaller diameter cylinder which would only work on length. That way you dont have that swollen look. I think it would be great for that little extra after a length workout. After you do you regular length workout, you could put the smaller diameter cylinder on and keep it stretched all evening long.. It would be more comfortable than one of those JES extenders....
But, back to my original comment about the mushroom cylinder, I think this would help dramatically for the head. It would be a great boost at the end of your workout.
