Premature ejaculation is, as you know, great. First, it's a real time-saver. You can finish the base act of copulation and be off and about your business. Second, you can save a TON of money on shady rent-by-the-minute motels, not to mention prostitutes (sometimes you don't even have to stop the car or -- for some extreme cases -- roll the window down all the way!).
As if all that weren't great enough, now it appears that the gene that makes you a premature ejaculator is linked to quick reflexes, or to put it another way: You're better at stop and pop
if you're known to pop and stop.
