By late 1985, Dahmer had begun to regularly frequent the bathhouses, which he later described as being "relaxing places", but during his sexual encounters, he became frustrated at his partners' moving during the sexual act. Following his arrest, he stated: "I trained myself to view people as objects of pleasure instead of people". For this reason, beginning in June 1986, he administered sleeping pills to his partners, giving them liquor laced with the sedatives, then raping their unconscious bodies. After approximately 12 such instances, the bathhouses' administration revoked Dahmer's membership, and he began to use hotel rooms to continue this practice.
