My girlfriend is 22, I am 38, she is an attractive shy brunette, I think I would give her an 8 out of 10 rating for her overall facial and psysical beauty, but she doesn't think of herself as being attractive.
She is the type of girl who is pretty enough to have alot of guys chasing her if they are in the same environment like a college workplace or party etc, but not that gorgeous that she would turn alot of guys heads if they saw her walking down the street.
I myself am about an 8 out of 10 type of a guy as far as my looks are concerned, I like girls to be at a certain level of beauty at least a 7 or 8 otherwise I just can't enjoy kissing and bonking them.
I have had gorgeous girlfriends in the past but every guy wants to steal them away from me and I always get into punch ups with these guys whenever I have gone out with them, so I stick with the still pretty but not so desperately desired by other guys 7 or 8 out of 10 girls with long brown hair these days instead of the long blonde haired 10 out of 10 beauties.
I often see ugly guys with ugly girls and I can't understand why they are with them, how they kiss and have sex with them, as I couldn't, I would rather wank myself than screw a woman like that, even if I had a head on me like a Bulldog I still wouldn't date an ugly girl, I would just stay single and visit brothels I think.
