Do guys need bigger dick

No. Most guys have all they need, and worry needlessly. Nor is there a way to make it bigger, if they want it.

wrong, pistashyos (i know i spelled it wrong deal with it) are beleived to raise testosterone, which should make your penis grow, you should find a difference after a few months (i did) and I'm twelve with over average penis about 3 incges larger than normal
