How Long Is Too Long?‏

The media really does play a number on us. They paint all these pictures of ideal sex, and then men feel like they have to live up to an unattainable measurement. The images of lengthy, orgasm-inducing sex all over the place can start to take a toll on our perspectives and expectations.
I came across an article that might help put your mind at ease. "Short sex is the best, say experts" details how a random sampling considers intercourse to be ideal if it lasts between 7-13 minutes. Sound about right?

This is generally an adequate time but you would never know it based on everything we see in porn, television, and movies. Trust me, most women do not want to be jack hammered for 45 minutes at a time. Men, of course, would like it to last longer because it feels so good. But a part of this desire, too, is, again, the underlying belief that they need to be studs and go much longer.
