Yes, that is rape. I am so sorry your uncle did that to you, that he put you in this position.

Has he done anything similar to you before? It seems you are in danger of him doing somthing similar again regardless.

I do think you should take active steps to protect yourself. I know how hard that is in a family situation.

Out of all the people in your family, or in your wider circle of friends, is there one person you feel you could tll about this?
