When I was 15, my boyfriend used to force me to have sex with him. So I discovered a trick: every time he tried to force himself on me, I would punch my knee against his groin and pretend I didn’t do it on purpose. Usually, he would stop then. But once, as I did so, he started to hit me and wouldn’t let me leave. So I went to my father, and together we told my boyfriend, “it’s over, get out!” I felt ashamed but I had been looking for a solution for a long time already.
