Probably because the cast of attractive men means most of the people drawing fanart are yaoi fangirls. Oh well, don't really care as long as the art is good.
To be fair, most shows with mainly female casts generate large amount of yuri images, and you don't see anyone wonder why. So is it really that strange?
