I don't know anything about the very manly little Mariusz (they didn't include the interview part of his audition), but his name suggests he might be Polish. His cock is most likely to please those who agree with the 18th-century painter Hogarth's aesthetic dictum: "The line of beauty is a curve."
That's BA's name for the series, so maybe you should ask them.
where is the XL please?
Handsome. Nice cock. Like the curve. Bet his buttocks have nice curves too, the kind of which serve to guide a man's big cock in to his aesthetically attractive butt...
