Premature ejaculation is caused mainly due to psychological problems. Premature ejaculation may be caused by stress, performance-related anxiety and other relationship issues. It can also be caused by hypersensitivity of the skin of the penis. You are just 21 and therefore, I suspect psychological reasons. You could have sexual performance anxiety and because of that you are unable to have normal sex with your partner. I suggest you to consult a psychologist for counseling. Take care.
