When I was 7, my oldest brother who was 16 at the time, began making me perform oral sex on him. All these years later it has come back to haunt me. I don't understand why it is bothering me so much now. I feel sick when the memories come back. It feels like it is happening all over again. I hate the feeling. I just want them to stop. I need to know, would this be considered sexual abuse, when my brother was only 16 at the time?
