In small rooms nearby, some men are having sex. A naked black man reclines on a sling in a room called ''the dungeon play area.'' Along a hallway lined with lockers, black men eye each other as they walk by in towels. In the basement, the mood is different: the TV's are tuned to porn, and the dimly lighted hallways buzz with sexual energy. In the common area, on the main floor, men in towels lounge on couches and watch CNN on big-screen TV's.
There's a large gym with free weights and exercise machines on the third floor. In its upper stories, the Flex bathhouse in Cleveland feels like a squash club for backslapping businessmen.
