Bathroom sex is the engagement of sexual activities in the bathroom or toilet, either private or public. Bathroom sex occurs in many parts of the world and in many places, including stores, hotels, bars, restaurants, airplanes, and universities. Bathroom sex is depicted in many films. There is specific jargon which is applied to initiating and having sex in a bathroom, as well as the sex positions that are most commonly used.
According to anthropologist Helen Fisher, when a person is in the bathtub with another person, they have removed their "defenses". Therefore, every touch during this time becomes a lot more intimate.[1]
