I'm a straight female, but I can still have an opinion, right? :P
I think it looks best if a girl is shaven, a cute little landing strio, or just very trimmed. It looks messy when she doesn't spruce up the hair down there, ya know? But then again I'm looking at this from an aesthetic POV, not a sexual one haha.
The only thing about shaving that I hate (as does my guy) is the stubble. I get it the day after, but since my skin is sensitive (even the skin on my legs) I can't shave the day-after unless I want to risk some nasty razor burn. :(
But I prefer myself shaven to be honest, even if it does have some cons. A little stubble, although annoying, is always better then razor burn!
