Well, I can suggest something thats a little tiring, but it works.
When you have a lot of spare time or your up late at night or whatever, watch some porn or something, whatever gets you hard.
Masturbate until you feel like you're gonna cum. Right before you do, stop, and let your penis recover. Breathe deep and close your eyes, take your hand off your penis. Just relax and breathe deep for a while. After about 30 seconds do it again.
Repeat 5 or 6 times for the first couple of days. (eventually, let yourself cum or you'll get blue balls ouch!!)
after a while you should notice your orgasms dont come on quite as fast.
Begin to repeat the process 9 or 10 times for a few days.
Continue at your own pace until you have reached the point where you feel you can have sex until you please your woman. :)
