Lets look back 30 or 40 years and see who was screwing whom.
1970–1979

Thomas Evans, Representative (R-DE), went golfing in Florida with nude model and lobbyist Paula Parkinson, who later suggested her lobbying techniques had been "unusually tactile".[49] Though Evans apologized for any appearance of impropriety, he was voted out of office in 1982. Future Vice-President Dan Quayle and Congressman Tom Railsback went on the golf trip too but were not implicated in the sex.[50] Marilyn Quayle said it was common knowledge that her husband would "rather play golf than have sex any day."[51] (1981)

Ernie Konnyu, Representative (R-CA), Konnyu was accused of sexual harassment. He had asked a female aide to move a name tag she was wearing because it was drawing attention to her breasts, about which he later said: "She is not exactly heavily stacked, OK?" In another instance, he reportedly touched the knee of lobbyist Polly Minor during lunch, which caused a scene. GOP leaders were unhappy with Konnyu's temperament anyway, so they found Stanford professor Tom Campbell who ousted Konnyu the following June.[56][57] (1987)
Jim Bates, Representative (D-CA), made sexual advances toward female staffers.[58] (1988)
