I think a co-worker died this way while out of town visiting one of our other plants. No one has said for sure, but context clues lead me to believe that the other co-worker that found him (after hotel secruity did a well check when he didn't meet up in the morning) discovered he may have been watching porn.

No asphyxiation or wrapped genitals or anything. Just laying in bed doing good old missionary wanking to a video and had a heart attack.

His reluctantly-estranged-but-not-yet-divorced wife worked under me at the same company and I had to tell her. That is something I will never forget.
