I watched a video that described how all the senses are used to determine attraction, or if a person would be a compatible reproductive partner. Basically, the first thing for most people is sight (physical appearance) then sound (tone of voice, in which certain ranges are typically considered more attractive). Next is smell (pheromones at play). Then it's touch (I forget what was special here). Lastly is taste; this is why sometimes a first kiss can cause someone to change their mind completely about a person. Personality is obviously important too. You need a partner who can raise your offspring effectively.As they say, "looks can open doors, but personality can keep them open". I think it makes evolutionary sense to first assess what you see, but then consider the personality after in a potential partner.
And fiction helps play a role in the attributes we find attractive, but there are certainly logical boundaries (i would never want a fae husband who only visited during full moons, leaving me to raise our half-mortal offspring alone).
Also, lol at your second point.
