Alrighty, penis size is a weak way to satisfaction. Mine is smaller than yours so I got ya beat there. It's for guys that don't know what else to do because just inside (about 2 inches in), the clitoris dips close to the vaginal wall. Now why is this important?

Because someone who knows what to do doesn't need to stick it in and hope he hits the sweet spot. Trust me dude, learn to use your mouth to please her orally and you can make her go blind and unable to speak. I'm not lying. You've got a whole body to work with, but your brain is your best sex organ. Get to know her body and how she acts. Learn to take her to that peak and hold her there and hold her there and hold ...

Now if she's just a size queen ... then she's no good at sex either.

Both of you need to make this relationship more about you both as partners and less about the size of your penis. If you nurture your relationships and learn each other, size will be almost completely irrelevant.
