My co-worker reported a similar story. Her husband had mentioned concern that being assigned a female partner on his job could result in situations that could be perceived as untoward. He is a strict Mormon who prefers to avoid any potential accusations of impropriety, and he was also concerned abut the potential for workplace gossip or public perception. Rightly or wrongly doesn't really matter, that was his concern. And he got written up for gender discrimination against the female co-worker.
