Or I might not. Originally (european Dark Age), Succubi and Inccubi were two aspects of the same demon. Their sexual interactions were exclusively meant for reproduction, thus heterosexual by design. Since they were unable to reproduce by themselves, they used their female form to collect semen from comatose males, then pumped it into comatose females. They obviously had very little understanding of genetics at the time, as human seed used to fertilize human eggs can only lead to a perfectly human offspring, unless being within a demon body somehow tainted the seed.
