The human protagonist is a bisexual dude who isn’t aggressively unpleasant. It’s sad how rare either one is.

Most ponies here usually are bisexual until they finally shack up with another pony.

From a nature point of view, it makes no sense as genitalia exist solely for reproduction which is only possible with the opposite sex. On the other hand, in a clearly horny-tastic species for a fanfic it actually makes a lot of good sense that they would be bisexual. Because of lust and the need to vent that lust, evolving in such a way would make sense.
