I definitely check girls out like guys do...I think. My friends and I tend to rate girls and what not. Kind of fun.
No real way to know, but i guess that girls look slightly different then men do, as all guys look at is boobs and bum whereas girls look more at the overall appearance, hair etc. Well that's my view anyways. I personally do check out the typical things but tend to look that little bit deeper. But cant really beat a fit girl with an awesome body!lol
That's one of the reasons I knew I was lesbian. All of the sudden I realized I was checking out girls the same way my guy friends did.
