I hate to be one of THOSE posters, but why bother with PE? If you’re truly 8*6, then you’ve got a titanic dick already. I totally understand the feeling of simply wanting more than you already have (regardless of how much you might have already), but PE really requires a substantial investment of time and effort in order to pay dividends. If you’re willing to put that kind of time into improving yourself, I would think you’d do better to spend it at the gym, or getting a master’s degree, or a black belt in Ninjutsu, or…you get my point.
I’m really not trying to dissuade you — you should definitely do whatever is going to make you happiest. Just something to think about…
