My hands are not that large, but, are strong, and I have some callouses due to having done since my teen age years, pull ups. I do several different kinds of pull ups, and it gets callouses , and, I accept those ones, it is protection, no injuries with discreet but sturdy callouses.Also, my knucles are a little larger due to years of punching bags and different work outs. Large knuckles , specially the first two ones, look good, girls constantly ask me about it.
I do not manicure my hands, never felt any need for that, I keep them cleaned, nails well trimmed, and, working in an office and in courts requires cleaned hands / nails. I only once manicured my hands at my GF's insistence. I did not like the results, looked too artificial. Never ever again.
When I work on my cars and motorcycle engines and suspension( avid performance enthusiast ) , I wear latex gloves, so my hands never show any trace of my engine performance hobby.
My hands are hairy too. Dorsal side is hairy, as well as my second and third phalanges ( middle and proximal phalanges ). My thumb middle phalange also has a small tuft of hair. I like it. I have found out, girls dig it too. Usually girls find it astonishing. That gives me the occasion to touch hands , and allows me to really enjoy female hands. I love those long fingers, womens' fingers appear to be too long for the palm size.
Womens' hands are enticing. When I enter in conversation w a girl, I like to study her hand movements, and, her hands in particular.
