Y'know, something else quite a few of you aren't factoring into the equation: "Beauty is in the eye of the beholder."
Just because YOU don't not personally find a person attractive, does not mean every other person on the planet feels that way

I'll give you a couple of example: There are women who are attracted to bald men, there are men who only are attracted to heavy women, there are people who only date people who are of a different ethnic group from their own, there are plenty of people who find bodybuilders of either gender "gross," need I go on?
Physical beauty is tenuous and ephemeral. What if you fall madly in love with a 10, you have a perfect courtship, you realize you've found your soul mate, you eventually marry and after 15 years of blissful marriage your beloved is in a horrible car crash that leaves their face and body scarred beyond what plastic surgery can repair. Then what? You stay with them out of a sense of loyalty but are revolted to be in their presence 24/7? You never hug, hold, kiss or make love to them again?
Then I'm forced to ask, was it ever really love, or just infatuation and you'd do just as well having a relationship with one of those $6,000 Real Dolls.
