Is it normal that i touch my sister sexually? (not what you think, probably)
First off: maybe this is weird in itself, but I have no other friends aside from my sister, who's 14 years old. I'm turning 21 and I'm a girl (kinda sorta). We've been best friends for four years now. I'm really asocial, so I basically spend all my time either alone or with my sister, playing games, reading or just talking.
We know everything about each other, and as I'm a really fucked up kind of person (hate myself with a passion, depressed for 8+ years, asocial, obsessed with ridiculous things like ensuring no one touches my stuff, always wearing men's clothes and short hair, kinda misogynistic... the list goes on.) I seriously dread befriending other people. Even if I wasn't the social cripple I am, I doubt anyone else'd accept me. Also, I'm introverted so it's just easier to stay home and retreat. And there I have my sister to cheer me up.
Lately, though, my sister has been going through puberty and we've talked really frankly about her period, masturbation, sexual fantasies and stuff. I've never experienced sexual desire, not really. I guess the antidepressants killed my sex drive when I was going through puberty. Well, I'm happier for it, really, because I loathe my body and everything about it and could never imagine having sex without puking, even if someone were willing to do it with me for some weird reason. (Did I mention I'm also obese? Yeah... But I'd hate my body even if I was thin)
Welp, back to my sister. She has been talking about sex and I've probably gotten a little too interested. Lately, while we've been sleeping in the same bed, I've kind of touched her sexually... but I never iniated it, she did. I was just hugging her, but then she wanted me to touch her, so I did. Even "down there", but I don't know how to do it properly, so not much happens when I try. She does like me stroking her hips, though. And she enjoys a little pain.
She's totally cool with all this, but I don't think it's normal, honestly. I could probably just stop touching her and let that be the end of that, but I don't know why should I want to? But let me clarify: I'm not attracted to her sexually. And she isn't attracted to me, lol, definitely not. But her pleasure sort of turns me on... really mildly, though, since I'm not sure I'm even able to experience full-on sexual arousal. And it's not like any other girl would ever want me to touch her like that.
One other thing: aside from this, nothing has changed between us. We're still friends and act precisely like before. And we don't kiss or anything, not even when I'm pretending to be her crush and lying with her in her bed. (Welp, another freaky aspect of it right there... oh well)
