I'm paranoid/obsessed with my and it's driving me crazy and I can't take it anymore!!!!?

http://m1136.photobucket.com/albums/Koolaidjungle123/?src=www. Okay I'm a 17 year old male and I been oversee about my ever since this girl called my cousin small when they had ... My cousin is 7 inchs and I guess I'm 4.8-5.2 inchs idk. I guess you guys can judge that. Now all my friends are above average like 6-9 and also I listen to rap and rappers always talk about how they have a huge ?? Now I want to enlarge my , as you can see I'm small in the pictures and I'm not happy with size so I heard of jelq excerises and I heard of alot of success with them and I want to do them so what do you guys think? Also I feel like I have a micro cause I'm small and do I? Girls now espically in my age want huge meaty and if we don't then we are considered worthless. In my school I hear it all the time of these girls talking about how there boyfriend has a big one and this kid sent a picture of his to the ladies and they all said he was huge. Also when guys walk away you can see a bulge coming out of there pants when there flaccid and that means there big and my penis doesn't bulge out. Also when I masturbate I only last up to a minute or two and I know that's sad. I'm a virgin also to begin with so I'm afraid when a girl touchs my penis might just *** right away and please don't tell me it's the motion in the ocean cause it ain't. I need some serious help cause everything I see I do I compare to my penis size and I feel even smaller. Can anyone please help me!?
