I once asked that question to an escort who was smoking hot, a great kisser, well hung and sucked, rimmed and fucked like a porn star. He was also married to a female, had two young daughters and was a Marine who had just returned from a tour in Afghanistan. He admitted he was totally closeted and fulfilled his desire to be with men by escorting. He said all his friends were either jocks or military and he had no one in his life to confide in. After we were through, had dressed and I paid him, he asked if he could hang out with me for a while and talk. We talked for an hour, three beers apiece, and then he left. Very sweet guy, unlike any escort I've ever been with, before or since.
