In many Asian countries housing is dense and there is a stigma about being heard while having sex.
Love Motels, as they are popularly referred to, are stocked with sex toys, sex chairs, a free XXX video shelf, and "couples" bath tubs.
Also, when young couples travel they often can not afford nicer accommodations, so they patronize these ubiquitous establishments.
*In Konglish, Koreans say or text mt for "Love Motel"
"We stayed at a love motel that had a dildo vending machine."
