A place where men go in order to have hot and horny sex with each other.
These places usually offer two options : renting a locker or a "room". Most of these rooms are small, but can be equipped with a TV (displaying gay porn) or large mirrors.
A decent bath house usually offers the following : spa, sauna, hammam, showers, dark/back room(s), movie rooms or TVs, a bar. Some bath houses also have glory holes, a movie theater, a weightlifting room, a large lockerroom, male masseuse, a swimming pool, etc.
I feel like having meaningless sex with a sexy guy, so I might go to the bath house.
I was into an incredibly hot orgy in that room at the bath house; the door had remained open and guys kept coming in.
