For women: I like women a bit older than me, I like plus sized women, I like slightly deeper voices, I like flat women, I like a chubby uhhh “mons pubis”, I like muscle women, I like pubic hair. There are so many, often contradictory, things I like that are broadly considered imperfections. Frankly, I just like women who aren’t the typical beauty standard.
For men: I like anything that softens them, makes them seem less aggressive. Some of these are pretty common (e.g., “twinks”) but I also like chubby men, short men, long hair and so on. It’s less broad than things I’m into with women and has a definite reason rather than being a seemingly random assortment of things.
That’s just physically as well. Wealth is a turn off, being really into fitness is a turn off, overly ambitious is a turn off (particularly for work). I like cozy introverts who just want to be content with life.
