My Penis In Itchy From Inside Specially Near The Head And Sometimes A Little Burning.What Can This Be?

It could be a urinary infection which is an infection caused by bacteria that has managed to get in.
It can be treated simply by antibiotics and you should be ok in no time :)

You can't diagnose what it is by just a yellow discharge... But you best get to a doctor as soon as possible. It may be chlamydia  or it could be an early indication of gonorrhea or even syphilis. Don't wait to see what else develops... Either one of these can be serious. And Amoxicillin will NOT touch any of these conditions.

It's clamidia all the way...go to the doctor and they will give you some pills and you'll be fine....lol

I would definitely go see a doctor.

Me too can anyone tell what to do to fix it I'm only 14 and I never had sex so its not gonorrhea or any of that I don't want to see a doctor tell me what I can do???

Ask your girlfriend where shes been the last month.
