There are a lot of things guys universally agree on. This is not one of them. Some guys love it, some guys find it utterly appalling. Personally I think it's hot. Whatever the case, be yourself and you'll attract compatible guys while sending away incompatible ones. Don't change it for the sake of getting guys.
Im guessing by your name your a runner. My girlfriend is a cross country runner and her body is amazing, her abs were not overly defined but she's skinny and has a solid stomach and looks and feels great.
