At first I hated the idea. I wanted him clean shaven from head to "down under". Then I didn't care as much. Now he trims everything. He has his beard trimmer and his special trimmer. And they are clearly marked. So my opinion I guess is it doesn't matter. But it's completely up to the woman in question when it come down to it. I find trimming the best option because it tames the masses and you don't have to worry about ingrown hairs or itchiness.
I think it's crazy sexy for guys to have lots of hair on their arms, hands, legs, and especially a little bit on their lower torso. Not a fan of chest and back hair. As for THERE, it's nice to be well groomed and trimmed.
It's kinda hot. As long it's not a jungle but some tamed hair is good.
Shaving pubic hair for both men and women at least once every month-40 days is a must due to hygiene reasons. Apart from that, I like a clean back on men. Moderate amount of body hair on arms and legs are alright. Very little or no chest hair is preferable for me.
