I think I am somehow being sexually harassed by my younger sister. Not in a physical way, it's more like she is trying to make me feel ashamed over my sexuality, like she's trying to destroy the little self-confidence I got.
For example, when I sit at my computer, she often rushes into my room and stares at me, saying things like "Whaaat were you just looking at?!". Many times she tries to pull my chair backwards, as if she's trying to check if I have an erection, but often she just gives me this creeped-out look, despite the fact that she never saw anything at all.
No one in my family has ever catched me looking at porn; due to the location of my room I can always hear people coming, so I have time to shut down whatever I'm doing. My sister is very manipulative, almost in a psychopathic way, and keeps on whining on our parents that she wants to switch rooms with me. She is very unstable and yells alot, so fortunately enough she hasn't gotten her will through, but she is becoming more and more skillful and refined in manipulating the people closest to her.
What to do?
(seeking professional help for her is not an option here)
How old is she, to begin with? If she's young enough, she might just be playfully exploring in the only way she knows how to, without really looking to the consequences.
If she's old enough to know what she's doing, however, I can see where the discomfort is coming from. Next time she does it, ask her: "Why are you doing that? or "What are you trying to find out?" and confront her with her actions. If you aren't blunt then she might not realize that it's not a game, and it really is affecting you.
On the flip side, if she actually is doing it to hurt you, and it isn't just a game to you, I'd go to your parents. Younger siblings often don't listen to their older siblings just because, so you probably won't be able to do anything if she really does have malicious intent. Go to the people she can't ignore.
Good luck!
Tell her seriously to stop it. Threaten to beat her if she doesn't stop.
If she continues, slap her. Again and again, until she stops.
Ask her for sex.
>>5 you're whack, but that might work LoL
maybe he just want some attention or didnt understand clearly why men likes porn, try talking to her about why she did that? if you understands how she thinks then you can get to handle her.
another option is only watch porn when you're sister is not around, lock your door or watch at night.
Keep on watching porn and jerking it. When she comes to your room again, "What are looking a... Oh", you go "Porn. What the Hell does it look like?!"
You are an adult and you have every right to watch porn and masturbate in your own privacy. She barges in and sees you jacking off, it's her problem.
Is your sister hot?
Hook me up with her. There are people in some parts of the world who'd pay a lot of money to sleep with a fifteen year old girl. Even more if she's white, assuming that's the case.
Don't worry, you'll never be annoyed by her again if you choose my solution. You can have her room and all her posessions, too, since she definitely won't be needing them anymore. I'm a man of my word here.
