Btw, assuming this is you, Susaz, I don't see someone of "below average looks." I was actually quite struck when I saw this picture... it looks like a painting I might see hanging in the Louvre from the 17th or 18th century. You have a very regal, timeless, somewhat exotic and striking appearance that could certainly be described as quite beautiful. Again, beauty is in the eye of the beholder.... and sometimes we are the worst judges of ourselves. (Though you certainly sound well grounded with a lot of self-respect so I'm sure nothing I'm saying is new to you.)
On a side note I'm sure we've all experienced meeting someone who strikes us right off the bat as highly attractive, but after he or she opens her mouth and a selfish or unattractive personality is revealed, we see his or her physical appearance quite different, as much less attractive.
Same goes for the opposite... we meet someone (or even see someone on TV in a documentary or special) who is not particularly appealing physically, but once we get to know them, a winning personality rearranges all those features in our mind's eye into something we love to look at and find quite attractive. Which just goes to show the beauty inside counts more than the beauty outside, in the end. Unless you are a model.
And finally I know for me, when I look at someone I love my eye goes to their 'flaws' in a loving way. Flaws make us all human, and no one is perfect, so when we see flaws in others (scar, wrinkle, lack of symmetry or whatever), it endears us because we know we aren't perfect either, so we relate to that little bit of 'individuality.' Thank god we don't all look like Barbie & Ken. In fact, very few do.
