I can understand somewhat slim girls but the thinner they get the less attractive they are to me. I find them as a turn off mainly because of the bones and the fact they look weak, sickly, fragile. Plus they lack any meat in the booty and breasts.
I basically find any female attractive but if they're average/thicc then that's the sweet spot body wise. Race is anything but white outside of redheads. Namely because POC girls always treated me fairly growing up, while the white girls were the typical TV portrayal of white girls. Eyes I love them brown and green, especially green. Hair color I like everything even custom colors like purple and blue or even rainbow. I don't like untamed bushes, at least tame the forest ladies, I do it as a man so can you as a woman. You can keep the leg hair and pit hair but at least tame the spot I'll be going down on.
When it comes to personality that's the biggest issue. The thinner chicks tend to be snobby, daddy's little Disney princess. They think they're all that and can't do nothing wrong that the world owes them everything for 'being hot'.
That's why I look at the 'average' build and other girls because they tend to be less bitchy and more down to earth. I've met less thin girls that are down to earth than average/chubby girls.
Also when it comes to personality I look for someone that loves animals, maybe wants children, has the instincts to raise a child, prefers staying at home watching movies and cuddling over going out and partying, prefers monogamy over swinging (which has become more popular over the years), enjoys games and cartoons/anime. Someone that enjoys the simpler things in life and doesn't expect me to give them a diamond necklace every week with lobster dinners and ferraris.
