"Some men are confused (or rather not as educated on the matter) and they believe that the outside skin get’s longer and thicker. That’s false. However, some men have false expectations; they think using a penis pump once will cause them to have a bigger penis permanently, and that’s false. As in the gym example before, you have to keep at it, and you have to practice to see results. Yes, early on you will see results like any newbie in the gym, but if you don’t keep at it you will see those results diminish,” says Dubois.
No, there’s no evidence that essential oils can change the size of your penis. If you decide to try an oil anyway, do a patch test on another area of your body (such as the inside of your forearm) to make sure you don’t react badly before applying it to the sensitive skin on your penis. Avoid getting any oils in the opening of your urinary tract, since this can cause irritation. Always tell your sexual partner if you’re using oils on your penis, since the oils might irritate them or cause an allergic reaction.
Penis pumps and vacuums are popularly used as sexual aids to promote erections in men. They are also used by some with the intent of increasing penis size. These devices are placed over the penis (and sometimes the scrotum) and use suction to engorge the penis with blood. If used consistently over a long period of time, they can cause the skin of the penis to become "spongy" and have a thicker appearance.
The vacuum pump. This is a cylinder that sucks out air. You stick your penis in and the resulting vacuum draws extra blood into it, making it erect and a little bigger. You then clamp off the penis with a tight ring -- like a tourniquet -- to keep the blood from leaking back into your body. What are the drawbacks? The effect only lasts as long as you have the ring on. Using it for more than 20 to 30 minutes can cause tissue damage. This is sometimes used as a treatment for erectile dysfunction, but has not been proven to actually increase the size of the penis.
