Sloppy men

[Silverobama]

A woman told me she prefers men who are neat and well-groomed, rather than careless or disorganized. Is it natural to say:

a) I don't like sloppy men.
b) I don't like messy men.

They're both grammatical but we're very unlikely to use the first. That makes me think you're talking about men who are a bit liquid, not very solid!
The second is OK but my first instinct wouldn't be to take it to refer to their appearance. I'd assume it meant those who don't put stuff away in the house and generally make a mess.

Why don't you have another go and see what you can come up with?

How about "I don't like untidy men". I think this one is good. I thought of these three words in the very beginning because they all have the same meaning in Chinese. Please help me with one that native speakers would use.

"Untidy" has the same connotation as "messy" (for me, at least). There's still the chance that the listener will solely think that the person doesn't keep their house tidy.
Since the woman used the word "groomed" when describing her preference, why not say "I don't like ungroomed/poorly groomed men". More everyday language might be something like "I don't like men who don't take care of themselves/of their appearance".

Also, consider 'scruffy'.
