Hidden Desires (a short story)

Lyle wasn't "in the closet" but neither did he advertise his preferences, and when hot college boy, Cody, rents his spare room, Lyle is sure that the guy is unaware he has moved in with a gay man. When Lyle quickly develops an attraction to Cody, he keeps it quiet as there is nothing about Cody that implies he swings Lyle's way - until he walks in on Cody in a compromising situation that leaves Lyle both shocked and surging with jealousy.
