I'm a Man Who's Attracted to Women and I Hate It!

Right now I'm at my local pool, there's a pretty girl she's wearing a bathing suit that's rather umm... showing. I can't kick it from my mind, she looks good in it, but I can't stop looking. The fact that I keep looking feels wrong, I hate it. It mostly feels wrong because I've never spoken to her, I don't know what she's like, yet I can't stop staring. I feel bad, I'm upset with myself for having impure thoughts about someone I don't even know the first thing about. What the fork is the point of being capable of being physically attracted to someone that I don't even know well enough to have an emotional attraction to. It's dumb and I hate it. I make myself sick. I hate these desires of mine. This isn't who I want to be. Please, someone tell me why, for the love of god, what purpose it serves for me to be capable of this feeling if I'm not even capable of getting a girl friend with my nonexistent social skills.
