How do you feel when guys check out your boobs?

Last night at an event honoring Michael Douglas, his father Kirk was caught gazing upon Catherine Zeta-Jones' breasts. She has a lovely décolletage and bountiful cleavage, but an older man checking out his daughter-in-law's rack? Kinda creepy.The "my-eyes-are-up-here" phenomenon is one that has probably existed since the beginning of time and will never go away. Men see boobs and they can't help but look. Whether we wear a turtleneck or a low-cut top with a push-up bra, guys like checking out our boobs.While looking through photos my friend took at my birthday dinner, I noticed a picture of my boyfriend staring at my chest. It was hilarious! Obviously, he's my boyfriend, so I'm not embarrassed or annoyed, I just think it's funny that he was caught on camera taking a peek. On the other hand, in real world situations when I detect a stranger--particularly a much older man--distracted and looking at my boobs I am completely grossed out and feel uncomfortable.Many women go out in revealing shirts with the exact intention of grabbing a man's attention, so why is it that in certain instances a guy taking a look makes us feel angry, annoyed or disgusted?How do you react when you catch a guy looking at your boobs?
