You could do that or could do the other approach not to come at all.

So you might try the google search for "pc muscle tantra"
and learn to control ejaculation. Or buy a book on this topic.
I don't know how male porn stars do it, but I suppose they use their PC-muscle, too.

So you can make your girl come numerous times and then come when you want. It takes some time to learn...

But normally after 15 minutes it should work without problems... unless you have some medical problems.

Don't think there is a surefire way, as it depends on the girl as well. One ex-gf actually preffered a shorter, intensive session then an hour long pounding.

I would suggest talking things out and trying to clear your mental slate first. Sometimes the solutions can be found just by exchanging thoughts and ideas with your lover.

Sorry, just an old cliche to throw in.
And a little post whoring.

First time should be the fastest as you have the most energy, aren't drained, and have the most sensitivity.

Getting in better cardiovascular shape would help - both of you.
Experience will too. So, ask Nike says, Just Do It.
Everybody has something that really trips their trigger and you know to keep it for later and such.
