I Am Getting Premature Ejaculation And I Am Only 15

hello, i need urgent help. Its been two months that i have been suffering from semen leakage and nightfall. Im tired of it and im starting to get concerned about whether or not this is going to make me infertile. I am almost 15 years old, and i need to find a way to cure this problem without medication, since im shy to consult a doctor . i masturbate around 2-3 times a week, but even if i stop for a while it doesnt go awaY. I dont know thecause of this problem. Also, my penis seems to smell bad.. Any way to make it better or causes of the smell? I want to get rid of these problems once and for all!!! Oh yeah and last thing.. Ive tried to perform kegels to delay ejaculation but i have seen no positive outcome. please help.
