Is it normal to sense "sexual attraction" by a family member?

Funny you say that because my family never even entertained the idea that iccould be being sexually abused. By him, or anybody. I actually was raped by some school boys that lived down the street from me who afterwards beat me and threatened to do it again if i snitched. So i didnt say anything for my safety. They didnt speak to me much after but would follow me around and call out names at me. I started throwing hints about it through poetry and would leave it out in the kitchen for all to see. But nobody seemed to notice. When a teacher found a similar poem in a folder one day by accident, they called me to the principles and asked me who did it. I was scared to tell them who did it. So instead i insisted on who DIDNT do it. They knew i lived with a male. I specifically said it was NOT HIM or anyone who lived near me. But they still arrested him. And i got disowned by the family. Forever.
