I think there's a lot of gross simplification in media from fans that any attraction is automatically sexual in nature.
There's a book on writing from way back by CS Lewis (yes, the Narnia guy), called the Four Loves. Short version, the 'loves' include empathy and a familiar bond, Storge, friendship, and that bond, Philla, the obvious bond of sexuality, Eros, and unconditional love, which he described from a spiritual/religious perspective. The book goes on to note that there is a lot of confusion in media about how people confuse Eros, or the sexual love, with the others. Thus, the discouragement to use Storge between two men or two women in media because everyone has to assume they're gay. Which is bullshit.
