Is it true?

I was just going through my old magazines (yes, i was that free) when i came across an interesting article in Simply Her, titled 'Tame His Libido'. What caught my attention was the following paragraph below:

"Notice how he comes home from a jog or tennis game in a fantastic mood? That's because exercise causes a rise in adrenaline levels and endorphin production. These feel-good hormones don't just make him feel like Superman, they also increase arousal and orgasm intensity, the effect of which lasts about an hour or more with just 10 minutes of activity."

And i wondered, is that true?! So u mean men feel more frisky after exercising? I thought they will feel tired and sleepy? Men out there who are reading this blog, kindly let me know. Hahaha....

Oh yah, the article forgets to mention, what if he loses his tennis game? Wouldn't it more likely that his mood will be bad than be interested in sex? Hmmmm....
