if you continue having trouble ejaculating prematurely then you can use a technique to hold the sperm back, which gives you less down time.
I read about it and have used it, and it does work.
You basicly exercise the PC muscle. This muscle is the one used to stop peeing, you can feel it right at the bottom of your shaft, once you learn to control this muscle and you are having sex, and ejaculate, you can stimulate this muscle for about 5 to 10 seconds or longer, causing it to hold back the sperm. This allows for a man to have more then one orgasm.
Once you find the muscle and learn to use it, its just a matter of exercise; practice useing it when you get free time, just start with 5 seconds and then go to 10 seconds at a time and so on and so forth.
I don't have PE myself, I just wanted to impress my gf at the time, and you can last as long as you want with this technique
