Is it normal to have very short time of ejaculation.

I m 21 year unmarried. I think there is a problem with me. During watching pornography I find my underwear wet in one or a half minute without any touching or rubbing. I use to masturbate sometimes and that will also takes few seconds to eject it out. I m in a very big depression about it. And my parents are thinking of my marriage. How to cure this problem and is it possible or not?
