If you're looking for serious and permanent gains, you need to at least invest good amount of time per day to pull, stretch, hang, jelq, squeeze, pump and edge. Notice I place "edge" as being last. Because I always end my daily exercise with 15-20 minutes of edging, which helps ease down the edema(donut effect) after a long and intense pumping workout.

If you want high erection quality, then try the Hi-EQ herbal tincture drink available on Ebay. You can make our own too by using any herbal extracts that have active ingredient such as icariin(horny goat weed). This is the key ingredient used to make Viagra. You also need gingko biloba which will supercharge your blood flow(induce blood circulation) and dilate your veins and arteries.
