Look, cortisol_communist, you're overthinking this shit. I mean, yeah, getting railed daily probably jacks up your testosterone, which in turn makes your beard grow like a weed. It's basic biology, honey. Just roll with it and enjoy the sex. And if anyone gives you shit about your beard game, tell 'em to suck it and keep on fucking. Ain't nothing wrong with a little extra stubble from all that action.
