I had sex with my cousin

So i remember when i was little around 6 y/o, i accidentally knew how sex works cuz i kinda came across to a porn vid. Idk how but logic is out of the question. Anyway, my cousin who is like a year younger than me watches porn, so we decided to try it out, so when he tried sticking his you know...down there into my umm yk, it cant go in cuz HES FUCKING SMALL-
but we stopped in the middle of it cuz i was disgusted for some reason.
