These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
The only notable and potentially homosexual around here is Aria's maid, Dejima, who enjoys sniffing Aria's used clothing and loves the fact that part of her job is helping Aria dress, undress, and bathe.
Actually, the joke is that it isn't a part of her job. She does it because she is a horny pervert and Aria is too dense to realize that there's anything wrong with it.
