While in the military, I had the good fortune to find myself dating European girls, many of whom don't shave anything. Some would trim a bit or neaten up for their bikini bottoms and all of the European girls I dated in those 3 years had a healthy and open attitude about sex. It was so nice not worrying about condoms! And all guys in the military know, girls overseas want to come to the USA. Marrying an American is one way to do it.
I had to come home on leave to get a little rest. Big change from the Socal girls I'd been dating, but the American girls were catching up fast, was my experience, anyway. To be honest, my dick has never known if it was in a hairy pussy or a shaved one. Nor did it care! The big difference comes into play when it's time to go down on her and give her that special treat. I love going down on a woman and the variations between women is a big part of what makes giving them head or cleaning them so much fun.
