It's often joked about. Sex that's over with so quickly the woman wonders why she bothered getting naked. Here are a few things you can do to avoid the 'Minute-Man' label.

Take Care of Her
First and foremost, I want to say, if you give her an orgasm during foreplay, you've accomplished two things: 1) She's taken care of 2) You've taken some pressure off yourself.

Wear a Condom
A condom is one solution, but may not be practical in a long term relationship. The thicker the condom, the more this will work.

Distraction
Thinking of other things for distraction is something that all men try at one time or other. Just don't think of something that will completely turn you off.

Change Positions - Squeeze It
If you get close, change position. You might also try giving a squeeze to the head of the penis.

Empty Your Bladder
It may help to empty your bladder before sex to ease pressure (stimulation) on the prostate gland.

Advance Preparation
Masturbate an hour or two before sex. This is what I recommend most often and seems to work for many men. You may also consider having sex again. It's always easier to prolong sex when you've had an orgasm recently.
