No offense to the ladies but on a good day they look like the Predator alien to me. Do straight guys find that a turn on? They must do ... but I can't figure it out.
Depends, when I was younger they used to seem weird but mostly because I was afraid of hurting the girl, they come across as more delicate then they actually are.
I got over it because of the awesome smug feeling of making a girl come, I used to be squeamish about going down on chicks but that passed as well for the same reason. Its an amazing feeling making a girl writhe knowing that you are controlling exactly what she is feeling.
As to Aesthetics, too much hair is a big turn off, but otherwise the look of a healthy vag is fine no matter what, its funny because they are so unique from girl to girl, even on what spots are more sensitive. Mastering a vag is probably the coolest thing in the world and you cant do that if you are going to worry about little things like how it looks.
