Keep talking until you have found an adult who will support and help you. You can call a community agency or hotline. Talk to a friend. Also, be a supportive friend if someone else asks for your help. That person could be a family member, a friend, a date, a co-worker, another student, etc.
Sexual assault is rare.
Only girls are assaulted. 1 in 3 young women and 1 in five young men will be sexually assaulted before they turn 18 years old. It's your own fault if you are assaulted or abused. The responsibility for the assault lies with the person who did the assaulting. Sexual assault happens because a person loses control because of sexual need.
