Is it normal sexual kissing with my friends when i was 6

Ok this has always made me feel uneasy and dirty.
so i faintly remember when I was 6-8, i used to go over to my friends houses and we would enjoy taking each others clothes off in her wardrobe and kiss, sometimes we would re-enact movie kissing scenes. I think this happened a couple of times with my cousin aswell.
At that age ofcourse I didnt know about anything extra sexual but is it normal to have done those things when I was that young?
Im a girl, and my friends were all girls if that makes a difference
