What else would an elf female be but a sex slave (to a stronger, more violent race)? Let's be honest, if they were built for anything else but svelte, effeminate, sexuality their most common depcitions wouldn't look like petite
(human) women with low muscle mass and french-model curves. The sexy versions are nothing else but the sex-toys of the fantasy world, and even when G-Rated and clothed they are frequently embodied by small, thin, women. Otherwise they'd be shapely or buff or strong, etc like the other "fantasy races" such as Orcs, Humans, Dwarves, etc. The fact that they ALWAYS come in smaller, lighter, (mass not skin tone) & more petite than any other races pretty much means they're predetermined to be what they are. Seeing them any other way seems like wishful thinking to me.
