Do guys hate body hair on girls?

It's as easy as a simple shave. Mustaches and happy trails are for guys only, in my opinion. Arm hair is generally okay as long as it's not out of control.

Also, it will pay to keep the hair that she does have trimmed and maintained.

Body hair on females is not normally attractive. The best thing that she can do is shave it or wax it to bring out features. Thats another thing too is to accentuate her best features, if she has a nice body wear clothes that show it, if her eyes are pretty bring those out with eyeliner.

Guys don't seem to like it much--and neither do girls! It's annoying really, since so many more people than you'd ever imagine actually have quite a bit naturally. It depends on what she has, really. If she's dark-haired, the best options are bleach for the arms, wax or bleach for the stomach, and lasering for the face, if she's willing to invest! If she has light hair, she can wax her stomach if it really bothers hair; however, laser treatments don't work for light hair--or red hair--and she'd need to go for electrolysis if she wants a long-lasting option! Do NOT let her shave her face--some say it will grow in thicker, but worse, she WILL end up with 5 o'clock shadow!

Body hair is normal on girls, some more than others, but mostly, girls just get waxed or shave, a little stache, I have that, I wax my lip. Some girls have to, it's no biggie.
on stomach, I wouldn't wax that personally, I would shave that, but that's just my opinion.
But do something about it, don't just leave it.
