I don't last very long during sexual intercourse. How do I improve my staying power? 

Saving yourself (and your pride) from the Great Unexpected Flood is not as hard. Yes, premature ejaculation can be embarrassing, especially as your partner tries to soothe your punctured male ego: "Never mind, it was still good, honey," How can you're explain to her that it could have been stress, anxieties caused by high expectations, or even just over stimulation? Or that an astonishing one-third of men under the age of 25 are prone to PE? 

Firing too soon is very common, and doesn't mean there is anything 'wrong' with your (most women usually need twice as long to climax anyway).

Assuming conditions are relaxed, you're comfortable with your lover and not sublimating personal problems, it's just a question of learning to get it right. Because you can master techniques until you have multiple, ejaculation-free orgasms, which also enhances your levels of sexual energy. 

A simple method is the stop-start one, which helps build an awareness of gauging the sensations leading to release. what's power without control? Simply put, your partner stimulates your genitals, and stops as you feel orgasm, approach. As you defuse, the stimulation is restarted, and so on. 

Another is the pause- Squeeze technique. Withdraw as your climax builds, and have your partner (on top) firmly squeeze your organ for a few seconds with thumb and forefinger, where the glans meets the shaft. This gradually leads to ejaculatory control. Relax your body as ejaculation nears, starting with an erotic massage. Breathe deeply, in rhythm together. Pressure on the perineum (about midway) also works. Move your sexual energy away from your genitals. Be vocally expressive, and let your hands foam your partner's body. 

Switch positions and experiment with which makes you last longer. Out of bed, exercise your pubococcygeal (PC) muscles, the ones that control urine flow, with alternate contractions and relaxations. You can do this anywhere, be it while driving a car or watching TV. 

Finally, remember it's all in the head. The one with ears! Communicate your feelings. Sometimes women actually don't want the guy to be banging on on, to prove his 'manhood'. And if you think of sex as a task, half the battle is already lost. Express yurt love, be vulnerable and abandon yourself to it, and the rest will follow.
