My girl is picky about porn. She's more about how the girl looks in the scene and the overall vibe/scenario than how ripped or hung the dudes are (though them being good looking def helps). Girls that are closer to her body type; small/petite, with smallish but real tits and pretty but normal looking faces (no copious tats, piercings, or weird hair styles/colors), and fair skin.
It also helps if the sex is rough. She's a sucker getting the shit fucked out of her.
