I don't know if what my brother did to me can be classified as sexual abuse. I was staying over at his house. It was late at night, and we were watching a movie. At some point, he asked if he could initiate some cuddling. I actually agreed, since we are really close and both enjoy physical affection. While we were spooning, he snuck his hand under my shirt. He didn't say anything, and I didn't say anything. As the night went on, he alternated between different caresses, kisses on my head or the side of my face, and words of affection. I idly stroked his arm back because I felt awkward just lying there. He eventually asked "is this okay?" in reference to his hand inching up my stomach. I was giving him the benefit of the doubt and still thought the action was platonic, plus it felt nice, plus I am a timid person and have a hard time with confrontation, so my brain thinks saying "no" to people is provoking them, so I said "yes". I didn't really want to say it I, though. I don't think I wanted to say "no", wither. I don't think I wanted to say anything at all. I was tired. We both were. His caresses smoothly progressed to the point he was caressing the underside of my breasts. That's when I started really questioning his intentions. He asked "is this okay?" again. I said "yes" again. When the movie ended, I got scared. I had been using it to distract myself from what was happening, and I was afraid that now that there was no distraction, he would shift his whole attention to me and try to initiate something; so I sat up. He lightly squeezed the underside of my breast as I did so, maybe on purpose, or maybe as a reflex. When he realized I was genuinely pulling away, he took back his hands, said: "I'm sorry. Your brother's a creep", and got up to take a shower. I think that's the moment I started freaking out. It's what confirmed my suspicions that his touches really had sexual intent behind them. I had been trying to gaslight myself into believing they were innocent affection, but those words were forcing me to face the reality of my situation. I remember running my mouth non-stop about random topics when we were having breakfast because I was afraid he was going to bring up what just happened and would want to have a conversation about it. I didn't want to talk about it. I wanted to pretend it never happened. I still try to. But it haunts me. He and his wife (who had been sleeping peacefully in their bedroom through the whole night) left early in the morning for their honeymoon (I was there to house-sit, and had come the night before to hang out with them before they left). Once I was alone, I quietly went to their bed to sleep (with their permission and insistance, since there were no other beds in the apartment). As I tried to fall asleep, I still could feel his hands on me, like a phantom touch. I broke down right there. I felt guilty, and disgusting, for not having stopped it and for having enjoyed it too. I felt like maybe I was the creep, and maybe I was the one turning this interaction into something inappropriate. The following weeks, I tried to suppress my feelings. Some days before Christmas, I was on a plane with my mother, about to start our holiday vacation. I was close to my period and my breasts felt sensitive. That triggered something in me and I suddenly teared up right there, in public. That vague ache reminded me of the feeling of that one squeeze he gave to my breast. My mother noticed me about to cry, but I lied and said that's just because I'm close to my period and feeling gloomy (I had been struggling with depression for a while, which she knew.) During the trip, I would get random flashbacks to that night, sometimes even accompanied with feelings of nausea. I felt like I was making my brain overreact somehow, since I hadn't been raped and I shouldn't be traumatized for touching that can barely even be considered intimate. When we got back home, I did something I'm not sure whether I regret it: I talked to him about it. I sent him a long text (he lives in another city, which actually made me feel safer about confronting him) which I barely remember anything about, except that it mentioned "that night" and how I had been upset by it. I broke down while typing it, and it probably wasn't very coherent. My brother sent me many short replies in quick bursts when he saw it. He apologized profusely. He said "I don't know what's wrong with me", "I'll get psychological help", alongside many things I don't remember. That had me freaking out a bit. What did he need psychological help for? Was he admitting he's got urges he can't control? But I didn't say anything related to that. I was afraid of accusing him, and I made sure to clarify I was also to blame for not setting down any boundaries. We were both replying to each other without thinking. We were panicking, and full of adrenaline. I was scared of losing him. He was the only connection I had in the city we both lived in (very far from our hometown, where our parents and my friends all live). I didn't want to upset him, because he's a very sensitive person and I already felt guilty for how I was reacting to it. We somewhat resolved the issue over text. Except we didn't. At all. I pretended we did, but I was still plagued by doubts and paranoia. More than the touching, what haunted me were his words: "I'm sorry. Your brother's a creep." They shook me to my core. All I had wanted was to be in denial about what happened, but those words wouldn't let me. The story goes on to this day, but I don't want to write too much about the aftermath of "that night", since I'd be writing for too long and I want to focus on whether it was an instance of abuse. At this point, I feel a little more grounded and able to accept that what happened had sexual undertones. I am still full of shame and guilt. I did consent to some of the touching. I'm not certain I wanted to, but it is something I did. That would usually make me think this is a consensual encounter and that I simply regret it now, but there are many factors that also contribute to my belief that this could potentially be an instance of abuse too. First of all, my brother was 38 at the time. I was 20, which yes, is an adult, but still; he is my much older brother. He was already nearly an adult by the time I was born. He's been a figure of authority my whole life, even though he likes to pretend he's not. He's a little clueless when it comes to what's appropriate or not in social contexts, but I do think someone his age should know better than to sneak his hand under his little sister's shirt and go up her body so much his fingers actually brush against her areola. Secondly, I am neurodivergent, though I hadn't told him at the time. However, when I did tell him, he said he already had suspicions. Regardless of that, I've always been quiet and withdrawn, so it upsets that he initiated touching under the guise of innocent affection and then expected me to be able to express my discomfort when it escalated without him specifying it was going to. I don't think his form of seeking consent was productive at all either. He only asked me if two specific touches were okay, and only after starting to do them. He didn't ask for explicit permission for anything but the cuddling at the start. What I want to say is that I was vulnerable. I am young, inexperienced, autistic, and he has always been an emotional support and almost parental figure to me. I don't know how he can be so naive as to think he doesn't have any power over me. Maybe he does know that, but wasn't thinking at the time. I still don't get why he would touch me like that. I find a little solace in thinking that maybe I didn't have any control over it after all. But I don't know. Maybe I did. I am an adult after all. And I do believe he would have stopped if I had told him to. But I definitely never gave any enthusiastic consent. I feel betrayed. I feel lost. I feel angry. I feel sad. I've been avoiding thinking about it for months. Tonight, it all came back to me once more and I broke down again. I truly don't know what to do. I don't want to tell anyone close to me what happened because I am ashamed. I certainly don't want to tell my parents. I kind of want to cut ties with him, but at the same time I don't because I truly believe he is remorseful about it and I don't want to make him sad. I can't help being naive. I don't know if that's comforting, or embarrassing.
