1st experiences

When I was really little, I saw my mom having sex. I had to be about 5 or 6 and I remember being in my bedroom and masturbating. At the time I didn’t know it had a name but I would touch myself and it felt good. When I was in sixth grade I was staying with my friends parents for a week during the holidays. If I was 10 or 11 he had to be 8 or 9. We would dry hump all the time until one time we did it without clothes on. It felt good when his thing got hard but it slipped inside me and I freaked out and felt dirty. I never told anyone about my early days of touching myself or humping that boy and I still will never tell anyone to this day. Do I need a shrink?
