Hot-but-self-centered, or well-below-average-but-deep?
This time, suppose your choice in dating is largely between two extremes, with no in-between: someone who brings you to orgasm JUST from looking at him/her but who's so self-absorbed you feel like you're working JUST to earn his/her attention, which is lukewarm at best; or someone who on your looks scale (0-10) measures around a 2--3 on a very good day--but who treats you like the most important person in the world, and who's also so smart she/he can discuss just about anything without coming across as a know-it-all.
In this fictional universe there's no "maybe something better will come along." Yes, you can opt to remain alone forever.
