Penis pumps. These plastic tubes create a partial vacuum around the penis. The vacuum draws blood into the organ, resulting in temporary size enhancement. Models differ, but all include a plastic tube and a pump operated by a hand bulb. You squeeze the bulb, which evacuates air from the tube, drawing a little extra blood into the penis. Just remember, the effect is modest and temporary.
The underside of the glans and underside of the shaft had the highest sensitivity rating for a significant majority of men, followed by the upper side of the glans, left and right sides of the glans, sides of the penis, upper side of the shaft, and foreskin (for the minority of men who were uncircumcised). The study findings were reported in the British Journal of Urology International in 2009.

Tip #7 – Stay away from the products with low quality or questionable ingredients. It is understandable if you opt for the cheapest product on the market, but it's not advisable. If a manufacturer uses only the top quality ingredients for its product then it's impossible to make a cheap product. We are talking about a long-term investment in your own health and sex life with the long-lasting consequences. It's not all the same what are you going to allow to become a part of your body and blood (circulatory) system. You know how they say, don't you? You are what you eat. Well, in this case, your penis is what you provide for it in terms of ingredients.
