I laugh when I hear the commercials. They play them during the Howard Stern show in the mornings.
If you want to increase your performance, all you need to do is go to GNC and buy some yohimbe extract. Get the liquid form, the pill form sucks. Put an eyedropper full under your tongue for a few minutes about 20 minutes before launch and you will be very pleased at the results. It's a sublingual and absorbs through your salivary glands.
Yohimbe (sometimes called yohimbine) is a tree that grows in central/west Africa. The extract is from the bark. It dialates the capillaries and increases the blood supply to muscle tissue. Weight lifters use it for body building. Since Mr. Happy is technically a muscle, well.... BOING!!! SCHWING!!
I have personally experienced as much as a 30% increase in size. It mostly affects girth as opposed to length, but ask your woman what she would rather have. Actually, I think mine would rather have tongue any day of the week. [:P]
Be careful with yohimbe though. It can really mess you up if you have heart problems. It will increase your blood pressure/heart rate and should not be taken if you have heart disease. It can also make you irritable... well maybe that's just from lack of sleep the night before... hee hee
