Do what you want by yourself, but if you compare shit with other guys, that makes you gay in my book. I don't lift shit but my dick, and I still got the balls to say "Fuck you" to anyone I want. But if working out makes up for the size of your dick or somehow makes you feel more like a man, then enjoy.
In the meantime, I'll sit back and drink this, and smoke this, and laugh watchin' your veins pop out of your head.
But that's just me. Do what ya like I suppose.
