The reason guys our age think this way is because people at school and stuff try to lie and say they have big penises and you have a small penis. After a while you will start to believe it. But don't worry I'm here for the same reason you all are. And just saying 5 inches is fine unless the girl has been screwed a lot before (that's when you know not to f**k her) but a virgin girl will take anything. Remember even your smallest finger will still pleasure a girl...if this helped leave a reply -- Daddy
If you read back through the posts on here your see it repeated many times what the average adult erect penis size is! All of you stop writing in asking the same question with out reading back to see if it's been answered before because it applies to all!
