I dislike slash as a genre and it seems to be especially ridiculous in SW where you have firmly established relationships without ambiguities. The idea that Han Solo, who spends a lot of time and energy trying to get Leia, would all of a sudden have eyes for Luke is absurd (Han has to be the most flaming heterosexual ever). And Anakin, who has clearly loved Padmé since a child, risks everything for her, and turns to the Dark Side to save her, would get into an almost incestuous homosexual relationship? It doesn't make any sense.

I've long thought about the whole appeal of slash and I think it comes down to two things. On a superficial level, it appeals to women who find the idea of two otherwise straight-acting attractive men being sexual with one another a big turn on. But on a deeper level, it's really about turning men into women. Sure you have f/f fan fic nowadays but lesbian slash is still dwarfed by m/m fic and the overwhelming majority of it is by...women. How else to explain bizarre subgenres like mpregs or how a manly man in canon is so feminized in these stories (usually the younger, smaller man is the more girly of the two)?
