for girth workouts to sustain erections longer while clamping/squeezing/etc but thanks to the "Ring of Power" I don't see that as being necessary and in fact I see it as a waste of money.
Well it works well enough for me, and Viagra thins your blood which is a big negative if it is used regularly like you probably would with Penis Enlargement. I generally try and avoid drugs that are not well-understood and man made if I can.
