I'm an 18-year-old virgin boy and I have been masturbating since I was 12. Now I recently noticed that during masturbation I can't last long very much. I ejaculate very quickly like in one minute. But I can remember that when I started masturbation it wasn't that short duration. Does that mean i'm going to have any kind of sex problem related to premature ejaculation or something like that when I will do sex. I still don't know if have any kind of problem like that (ejaculating too early during sex) cause as I said i'm still a virgin.
