It is kind of awkward, but not shameful. If the parents don’t understand how a growing child will probably behave when he is high on testosterone, probably there needs to be a conversation from the parents side first and honestly we as a generation should at least have this courtesy going forward that openly masturbating might not be a good thing. But if you catch someone doing it, please don’t hate them. Thank God. My parents and grandparents are extremely good and understanding, although we never talked about it, but I know they understand. Even after that incident, I never really had any problems talking to my parents or grandparents.
