Hello, I'm a 21 years old adult woman. When I was a child (11-12 years old or younger), I french kissed my little brother (6 years younger than me) as a game, saying things like “let’s kiss like grown ups”. This happened a few times (4 or something) and my mom saw us performing it at least one time. I do remember that mom said it was gross (our first language is not english, so I don't know if "gross" actually catches the meaning of what she said. It was something like "¡qué asquerosos!"), and we laughed, literally sucking each other tongues, because she didn't seem mad, just weirded out. I felt nothing like arousal while doing so (afortunately), but I think that one of the times when we kissed my motive to do it was because, in school, I heard of a method for french kissing and I wanted to try it (it was something among the lines "if you move your mouth like you're saying the name of the person you're kissing, then you will be giving a good kiss").
Out slibing relationship is good, specially considering our conflictive family and the fact that he's now adiccted to games (he interacts much more online that with people in the house, and I totally understand his reasons). Neither of us trust that much in our parents, at least emotionally speaking, so the people we are most close within the family is each other. We've always been very physical with each other. And by that I mean hug and peek-like kisses. In fact, it wasn't too much time ago that we stopped giving each other peeks on the lips, and it was because of my insecurities. Although I've heard that kisses are normal depending on different family dynamics (my mother always gave us peeks), someone said it was weird and I worried a lot. I feel very motherly towards him, or at least I felt that way in the past, like he would always be my little baby. Don't get me wrong, I've never been in charge of his meals or bathing him, it's something more emotional. And so, we always showed a lot of physical affection, plus always saying how much we loved each other. All of this in a way that always felt fraternal, nothing more.
When I kissed him the first two times I recall it was because I wanted to know how it felt. I stopped as soon as I realized it felt like... nothing. We did it with our eyes open. I did not feel any arousal in any of the kisses we shared (fortunately), and I think (being absolutely unsure about this memory) we even tried to imitate the "mmmh" sounds at leats one time. The later times it was a mix in between that experimentation and of we trying to be gross, specially with the tongue sucking thing (just as we sometimes licked each other in the face trying to gross out other people or ourselves). I was the one who suggested it, and he would agree. I think I would've stopped if he showed any signs of being uncomfortable, but we just carried it like it was nothing. It felt like the plain flavour of saliva and tongues and nothing more.
For me, and for a long time, this was normal (to think I didn't even count these kisses as my first ones!), because we trusted each other and we were always very affectionate, plus it didn't have any sexual outcome, or so I thought. Now I know it was wrong to experiment with my little brother, because the age gap is huge, and I've learned we were in different development stages. I should have known better. I know I knew better what a kiss was, or at least I knew it was a grown up thing. I kinda resent my parents because they should have separated us and they should have scolded me instead of reacting like it was nothing, but the thing I want to know (and I'm more afraid of) is this: did I sexualy abuse my brother?
He's 15 now. I've asked him before this year if he ever felt in any way sexualy abused by me. I was insecure about all this issue of having been too physical with him, particularly because sometimes I grabbed his chest. He said it was ridiculous for me to think the chest thing was abuse, and kinda gently, kinda laughing he told me to "seek some help" when he realized how worried I was. But the thing is, I never asked him directly about the kisses, and I'm not sure if I want to. If he doesn't remember, I don't want him to suddenly remember it and have bad memories or feel bad. Plus, he's a teenager, I don't think he'd be comfortable talking about this with his big sister.
I'm asking here because I'm a little desperate for answers, and the guilt is consuming me. I've having a lot of troubles with intrusive thoughts about guilt in the last months (regarding all important aspects of my life. If I resolve something, I inmediatly jump into another issue), and so I'm going to therapy for the first time next week. I refused in the past because I was afraid, but this is something I can't ignore. If I've hurted him in any way, I think is going to be really hard, if not impossible, to forgive myself.
