I voted for 'Other,' because I'm conflicted. On the one hand, I'm flattered when the opposite sex stares at me, assuming I notice them staring. A large portion of the time, I don't pay attention.
On the other hand, I feel uncomfortable and embarrassed when I'm stared at. My instinct is to not be flirty and smile or something; instead, I pretend like I don't know they're staring and just move along. I have no idea why this is my reaction. Typically, this is my reaction if the guys are mildly or very attractive to me. I was in this situation the other day. It was kinda hot out, so I decided to wear one of those maxi skirts with a tank top. I was walking from my apartment and two mildly attractive guys passing by stared right at me; they even went out of their way to turn their heads back a bit. Needless to say, I felt embarrassed and pretended to not notice.
