I'm kinda in the same boat as you man. I was very loosely circumsized, and therefore have a lot of extra skin. My skin usually only covers about 1/2 of my glans, and I keep it that way. I've noticed that if I keep some skin covering the glans, the part that is covered up tends to be slightly moist, the skin is softer and more sensitive. I'd keep it covered up, but its really up to you.
