Do I have it? I am a virgin, 16 years old. When I masterbate to porn i can come really fast (3-4 mins) unless i keep stopping. So when the real thing happens and I am with a girl will i look like a fool??

probably will kiddo, use your other tools first, tongue fingers. you gonna come quick the first time, you could always think of your granny or something, may delay the inevitable by 30 secs.

The idea is not to masturbate and get off as quickly as possible. The idea is to teach yourself to go more slowly.
That way, when you are with a partner, you can concentrate on her - women take a much longer time than men - and you won't have to worry about premature ejaculation. Teach yourself some techniques that help you to prolong things.

when you actually have sex for the first time you will ejaculate quicker than you will while masturbating.....but no your body will begin to adjust and you will be able to go longer.....you are a healthy normal young man
