is it possible to have experienced childhood/teen sexual abuse but have no memory of it?

i feel like i'd say, no i have never, because i don't remember but i was reading a few things on it and a lot of the symptoms ppl talk about were very much me and as an adult i struggle with issues touching and being touch, the idea of sex terrifies me and i can't be in relationships

i am just wondering if i am nuts or if i am forgetting something major somehow? seems weird i would not remember

one key thing is i remember being about 10 or so and constantly playing barbies so i could do sexual things with them, not me and them but using them together in a sexual way. i always was touching myself etc, i remember those things... i am freaking out. help!
