The following presumes the person asking is male: If you're in your teens... guess what, you're pretty close to normal. (Teenage boys are notorious for blowing their load early.) If you're not... there are desensitizing creams and things you can use, to slow yourself down. A condom can help limit sensitivity also. "Warming up" before a date (aka "massage with release") can help with jitters, and the second time around happens more slowly. Distracting yourself can help; the typical diversions are to think about Baseball or taxes. (Other sports and expenses also work.) Foreplay with emphasis on her pleasure can cover a lot of ground. If these things don't help, you could be experiencing a condition called premature ejaculation. There are different causes for this; a visit to a doctor can help. If there are possible psychological grounds (too many to explain here), a doctor may refer you to a therapist or counselor.
