I definitely agree with the guys here about shaven being better, then again it's my own opinion.
Confirming the fact that mainland girls are less likely to shave down there (at most, trimmed a little to keep a nice shape), they even frown upon a man's shaved private area. There's been a few occassions when I've had 'lightly' negative comments about my shaved/well kept pubic area. Mainly, they say it hurts when the stubble rubs against them.
However, I've only had positive comments from SO's, so I don't care what the WGs say...
