Sexual harassment is unwanted sexual behavior. It may take different forms, including:

Physical contact
Grabbing, pinching, touching your breast or butt or other body parts, or kissing you against your will.

Sexual comments
Name-calling (slut, whore, fag), starting rumors about you, making sexual jokes at your expense, or making sexual gestures at or about you

Sexual propositions
Asking you for sex or repeatedly asking you out when you have said no

Unwanted communication
Phone calls, letters, or e-mails. These can be mean, nasty, or threatening, or they can seem flattering or nice but still make you uncomfortable.

These are only examples; there may be other forms of behavior that are not listed here but still can be considered sexual harassment.

Both the harasser and the victim can be either male or female, and they do not have to be the opposite sex. The harasser can be another teenager or an adult.
