mm, sorry, you fail again. you assume that all powerlifters are superheavyweights with 50" waistlines. as though any prospective sexual partners give a rat's ass about symmetry and proportion. they just know two guys have muscles. take a powerlifter and have him diet down to 10% bf and the average person cannot tell the difference between him and a "bodybuilder".
also, realize that for the whole 'sex' angle a dude with a good personality and abs will outperform some lunkhead with 20" arms. if you're exercising to get ass, apparently you've got something that you need to overcome, so you're trouble as it is.
