manicured and chipped yes but we dont really have a big care for it as woman do. Girls always check our nails make sure it clean and not dirty and dont like to be touch cuz girls are more cautions about that, Some of ous girls can really care less but i do look at manicures only cuz i kinda into fashion so i like see girls with pink bright and lovely or just dark black nails for that goth look. But ea as long they not chipped and toenails we hardly ever pay attention. That why hear many girls say we dont notice things when girl ask "baby see anything different about me?" and we say no when it was u got a manicured.
I notice and so do most guys. Few care, but it's still important to keep them looking well and healthy. Guys probably will notice at some point if they see you often. But that's not really why you need to take care of them. You should be doing it for yourself and your own health. It's your body.
