The Size Matters Beginner Pump is simple, but does the job!Who doesn't want an unusually bigger and thicker erection on demand? If you're not on a serious pumping regimen, then this is all you need. Just slide your cock through the comfort sleeve, and pump the bulb until you like what you see. If you go a little too far, hit the quick release button. If you are trying to cause some permanent growth, our best advice is to take it slow. Have fun and don't hurt yourself. If you keep huging your cock it may not go back to its original size.
