a straight engaged, very cute 28 yo friend, co-worker, stayed at my apt years ago, I was 33, and shared my bed, too drunk to drive home; i started sucking him in the middle of the night, he woke up, figured he'd be mad, but he told me to turn around, so we could 69, both cumming in each other's mouth, about the same time; he was embarrassed in the morning, wouldn't even talk to me, and never accepted my invitation to come over or go out again. i think all guys will have gay sex, in the right situation, as long as they think no one else will know.
