sorry i just may have gone a little over the top and im ANYTHING but political correct (trust me they don't call me teacher terror for nothing) anyways i always thought that it should be possible for the uhm less attractive races to romance npc's BUT it would indeed require some stats to be high like IN or CHA and perhaps even WIS or STR that the other races would not since you dont have the looks so you'll have to talk your way into there heart (that sounded way to romantic for my liking awell)
Believe me, He's way to political correct, right Peter B)
