Unless they were British.
Guy Francis De Moncy Burgess, the Burgess of Burgess and MacLean's infamous flight to Moscow after being tipped off by 'Kim' Philby that they were under investigation. Burgess was one of the Cambridge Four recruited by homosexual Anthony Blunt, a talent spotter for the KGB.
Burgess was blatantly and outrageous open about his deviancy both at home in the UK and while stationed in Washington DC. While the older Blunt claimed not to have had a sexual relationship with Burgess, the KGB had established a section know as "The Sparrow School" for the explicit purpose of using any and all kinds of sex to entrap targets into spying for the USSR.
Amusing side note: Google search revealed a private investigative firm called Burgess MacLean. Discretion no doubt guaranteed. Real or just a clever CIA front, or even FSB joke. ;>)
Burgess MaClean could be an old family name. Probably a dozen of them around.
