Well, I definitely have different tastes to you. If I read a genderswap fic, I have to have male/female. If the base pairing is slash, that means I only read it with one character swapped.

I blame this on simple preferences: I'm straight, and I just don't get femmeslash, so swapping both sides of my slash pairing fails to appeal to me, while a het version of them will do just fine.
