I know that there have been plenty of times in my life where I have an insane attraction to a girl that, by conventional standards, would not be considered pretty and possibly even ugly.

I have no idea where this attraction comes from, but I would assume that everyone has them.

Isn't it possible that even loser neck beards would have a few women that found them really attractive?

Wouldn't "be yourself" and "put yourself out there" be sufficient advice given this phenomenon?
