Nudes of this water-polo player here and here. On the SPEEDOS-OFF site, he wears a 100% nylon TYR Destroyer water-polo brief. Which means he can rub bulges with another player wearing nylon and he’ll

rubbing against lycra feels like you’re rubbing a tire on asphalt. Of course for this shot he’s wearing his team’s Speedo Avenger water-polo suit.
