My best friend, and neighbour from the age of 2 and I were very close.
In first year of High school he got hold of a porn movie from his brother (they were illegal back then).
We are in his family TV room with blankets covering any signs of arousal.
He suddenly pulls his blanket off and says "look".
Then he asks me to do the same.
After watching more of each other than the movie for a while he suggests we try stroke each other.
A mind blowing experience that lead to more play and experimenting for the physical pleasure.
Then girlfriends came into our lives and the play stopped.
Zero regrets and happy to have had the experience.
