So for almost ten years my brother and I would play this "game" where we would act out BDSM stuff (with our clothes on luckily). I was 5 when it started and 13 when I finally got up the courage to say no, before that I didn't feel like I could say no. I have talked to a few people and they all seem to think it was sexual abuse because my brother is older (21 months older to be exact) but by law it wasn't because he would have to be two years older and he is shy of that by three months. I don't know what it was, I know I was a "willing" participant - as in I didn't fight him off - but I knew it was wrong. I feel awful now about it and can't believe that we did that. I feel also that I am to blame for what happened because I should have said no and it would have stopped. Well I did say no a couple time but he convinced me to do it but it was still my choice. I talked to my brother last year and asked him if he remembered and he said no and seemed really confused. I feel like he couldn't have forgotten but I don't know.
