What do women think of a penis that is smaller than average?

Hey there, I am a 17 year old guy and my confidence has gone all the way down due to the size of my penis. It is extremely small and I am not joking when I say it's just about 2 inches (5 cm) at erection. I have always been feeling anxious of it and yesterday, one of my closest friends, gave me a really hard kick to that area and I am still in quite a bit of pain. From that point on, I am so scared to the extent that my thoughts have been nothing but thinking of having my penis cut off as I don't believe that there would be any point in living with such a small thing whilst my friends have bigger ones. I am going to the doctor tommorow and I am so nervous as I don't want them to look at it.<br><br>I am pretty sure that I will be single forever whilst my friends easily hook up with girls. What would you think when you actually see it?<br><br>Does it even make sense to live with such a thing?
