The reason I know size matters is because sometimes I bang women using a large dildo and there is a huge difference in how they react.

The difference is crazy. I can go deep, I can hit the bottom of the pussy, I dont have to work as hard, it hits all the spots that mine doesnt. Women get wetter and make much more noise and have more involuntary muscle contractions due to bigger orgasms. If I had a penis that big, I would show it off everywhere. Women would brag about how big my penis to other women.
