You may not already realise it but there's absolutely no reason why you can't grow
your penis to be anything up to a HUGE 9 inches! I'm not saying that size is the only thing that matters but if you are small then you don't tend to feel as confident as the men who are bigger - and that definitely comes across when you talk to woman. I have experience of it myself because I only used to be 4.5 inches and at that size I just didn't feel like a true man. It didn't even really occur to me until I got into my twenties and started dating - as soon as I realised I was a lot smaller than most I decided that I needed to do something about it...
