Hello AnonymousID, thanks for talking to us, it's not something that would or could easily be discussed with people you don't know, but we don't judge, we only give advice from our own experience or suggestions, so please don't be afraid.
You were young and with someone the same age it's easy to understand how a little coaxing could encourage one another, we were all kids once and copied, demonstrated, enticed and certainly wanted for our friends to join in.
We didn't know what it meant or the repercussions involved or whether our parents would find out and then discipline us, that was the thrill and excitement of being young no matter what it entailed.
Young boys used to satisfy themselves and if caught, demonstrative words would be said back to us, but this was unable to stop us, perhaps for a very time, but it continued on.
Whatever happened is a childhood experience and has possibly happened with other children on the process of learning.
You were young and didn't know what was right to wrong, so please don't punish yourself, just as another example, young kids used to smoke mum and dad's left over cigarettes or drink any alcohol left after a party, and heaven forbid if their parents found out.
Take care.
Geoff.
