size doesn't matter

...why is 7" the most popular size of dildo that is purchased when the realistic average is about 5.5"? This is a real question, I'm not trying to be sarcastic with this.

I don't think you've been a teen if you weren't insecure about it at some point. I know I'm 18, but 4.9 inches (erect) seems a little small. But I don't think I've ever seen a change since I was like 12 or 13, it's forever been that big, whilst I've continued to grow. I have always felt insecure...
