Big noses... especially if there's a fat knot on it. Almost makes it look like a tiny elbow on their nose. Like the one in the pic (to the left, obviously). I don't know why, I just really don't like it.

This is gonna be petty and ugly. I am not very handsome, so this is maybe just me being stupid. However, I would imagine any large warts anywhere on the body would be an issue. The obvious as others have posted would be someone who doesn't look like they've hit puberty yet, any features that remind me of someone I find repulsive (so highly dependent). Another thing perhaps would be if they were bald (I'm sorry, like maybe if I got to know them first this wouldn't be an issue? But this is a post where I'm just being very picky). And again this is a bit extreme, but if they were missing any limbs I don't think I'd date them. Perhpas another one would be if they were missing their fingers or toes (maybe a pinky or pinky toe). One I am sure of however would be if they had teeth or scars that indicated heavy drug use, I'd be friends maybe, but I don't think I'd date them. Oh, this one may be a bit obvious, but if they were CURRENTLY pregnant, that'd be a hard pass. Some other ones I suppose would just be signs of chronic illnesses, any spinal issues/injuries or missing hands, feet or calves/shins. I have plenty of respect for disabled and amputee folks, but I'm not terrible interested in dating one (I mean at least off the bat). Finally, to answer what I think is your real question (feel free to message me), I don't think there's much that would make me go "ew no." (I mean a swasitka might do it, but not much really that isn't exceptionally rare or serious.
When a girl or woman talks like a guy, acts like a guy, and behaves like a guy.. and no i`m talking about a trans or a lesbians that acts like the guy, but really just a straight girl or woman that has the behavior of a man... that instant turn off for me lol
