Well, I have found the best way to research something is to personally experiment and analyze it.
So, take a large quantity of male endowment pills (such as Viagra or Levitra), and occasionally giving yourself shots of adrenaline (use an EpiPen, insert on the exterior portion of the meaty part of the thigh) Once every three hours.
(And no, I'm not being serious)
Now being serious, let me know the results of your research. It is rather interesting.
