Probably the most underestimated feeling ever: Love! Many people will fight hand over tooth the idea that lust and love are essentially different forms of the same feeling, but I beg to differ: it simply means that we change the set of preferences we appreciate in our partner, as we get to know one another. And where some will want to know if sexual attraction is fine before romantic attraction comes into play, others will want a deep soul connection before letting anyone come close in the sexual area.
