Angelina i can only give one answer but i have been educated by several people
My answer is all of them. I learned about it at school, I have read about it and have watched porn when I was younger, I have talked about it with my friends and my parents also explained a lot to me, including why my father thinks it was best to keep me belted. Before I had the belt I masturbated a few times, but between the day from which on I had to wear the belt until marriage, I had no experience at all.
