I have these "memories"

Well growing up I have had sexual nasty experiences.I remember my cousin doing nasty things to me her making me do things to her. I also have other memories with girls from when I was like 7 8..I feel soo disgusting and nasty. And it makes it worst...

because Im a girl too. Sometimes I want to tell someone, anyone but I dont want to make a big deal out of it, I just want to get it off my chest. I guess this is why I want to be a pschologist for sexually abused kids, but is this abuse? I dont know..but every once in a while I have flashbacks, which make me feel ..undescribable..

Well, I think you should tell someone. It happened to myy friend and her sister, her older sister was 'testing' stuff on her. But they were young, and I know its not an excuse, but they were 'close' Yeah, I know :S

If you tell someone, it will probably make you feel better about yourself, and you'll stop getting flashbacks of it.

Sorry, I know its not much

The same thing happened to me as a child I was aprox the same age and the girls were the same age as well. They were my cousins and neighbors, I felt really dirty about it as well but I have come to the conclusion that there really was nothing you did or could have stopped. I had spoke to family members about it and they said its a testing stage children go through and they all went through the same thing as well. If it really does bother you you should see someone about it. If you wanna talk funmail me.

You said it yourself:I just want to get it off my chest
Go see a psychologist, whether it's one trained in sexual abuse or not, isn't that important. Its finding someone you can talk to and getting things of your chest and mind. I think you'll feel a hundred times better once you do.
To answer you last question, any type of sexual activity that is forced upon you is abuse. There are normal childhood games like doctor where children may touch each other but a child takes part in this willingly and never past his comfort zone. Also, even if what you've done seems harmless to others, the fact of the matter is, it is bothering you and that is why it's important to talk about it.

You might be feeling ashamed, but it's so common for kids to play in this way and it's generally not very harmful. Sometimes it helps shape the way we are and the things we end up feeling excited about...

If you believe it's interfering with your everyday life, you should talk to someone. If not, chalk it up to normal childhood stuff, and know that you're normal and healthy.
