Is it normal i perve on girls?

I'm a straight girl. Whenever I'm on the internet, browsing facebook, if I see a hot girl I will click on her and check out her photos. Or if I'm walking down the street I will "check out" pretty girls. I dont usually fancy men that are conventionally good looking although I do love sex with men so I don't think I'm a lesbian. Also I dont want to have sex with the girls I look at, I just like looking at them...like I find them fascinating. AM I NORMAL?!?
