Why do men just over sexualize?

I'm an attractive curvy woman and people generally believe that I've had cosmetic surgeries. I haven't had any and people swear that I'm lying but I ignore the stupidity. Why do men automatically sexualize me? I dress classy and carry myself like a respectable woman. They also make horrible assumptions about me like I'm actually a gold digger, whore, or just someone not to respect. I've literally never had my first kiss before and I'm 24 years old. But when people see me they literally think the worst about me. Women automatically hate me as well. They try to paint me as if I'm out to “get their man” because I'm friendly. I'm normally pushed out of social circles. But what is up with men and very sexual behaviors. It makes me uncomfortable..
