Was molested by a cousin?

I dont know if I was really molested. My cousin the same age as me when we were younger probably younger than 10, I would take my butt out and he would play with it and we would play sexual truth or dares. I remember this and started to crave sexual things. I remember being weirdly sexual as a child where I would watch porn and dirty talk to random people online. I was always horny and would do weird things to try to help myself. I was only probably 10-14 maybe younger when I was doing those things and it carried on a bit. Could what my cousin and I did be the reason I was so sexual as a child?
