Yes, granted, speedos aren't that popular on US beaches. And wieners might not feature on TV as much as boobs or butts (including male butts).
However, didn't you guys give us sagging? Sagging = guys displaying the waistbands/brand names of their underwear above low-slung jeans/shorts/trousers. Personally, I find sagging pretty erotic, especially if the guy isn't wearing a shirt.
A certain pop star (who shall remain nameless) takes sagging to a whole new level. In his stage performances, his whole backside and half his crotch are hanging out of his pants as he struts and gyrates to screams of female adulation.
So ... American culture is very uptight in some ways and very raunchy/suggestive in other ways? This pop star definitely has a mainstream following.
