the Jester
Legend
Most but not all are straight, and level of promiscuity varies between characters from "frigid-or-repressed" to "try-anything-anytime" to "only-within-marriage" to "can't-be-bothered-I'm-too-busy-adventuring" to various other degrees - they're all different.
On that score, my favorite of my characters was a very hot female elf who would be happy to sleep with anyone once she got to know them a little, but the catch was that, for an elf, getting to know you a little usually took longer than a human lifespan.
