Montana,
I think you’re missing the point.
Fact: You’re not small. You’re not even average. You’re large. Look up the statistics on the net if you don’t believe me.
So given the fact that you’re large, and that she called you small, she lied.
So even if you grow your dick to 10 inches, what happens if another girl lies to you and says you’re small.
Are you then going to say to yourself ‘That’s it, I’m going to grow a 12 inch or 13 inch dick!’?
Of course not, that’s ridiculous. You have to shrug it off. She just wanted to hurt you. The fact that she had to lie to you to make you feel bad tells me that you must be a very decent human being. So go forth and enlarge your penis like the rest of us, but do it believing that you are already large no matter what this lieing woman says.
