It might be appropriate when talking to boys especially about the practice of choking oneself for pleasure to discuss masturbation, but apparently an obvious and well known part of the issue isn’t even addressed in the news article. I know it’s ‘icky’ and makes people have vapors despite 90% + of men partaking, but dealing with a health issue should be dealt with as a health issue and not some bizarre morality dance that has no practical meaning.
Of course, the signs of trouble include the worthless:
• Locked or blocked bedroom or bathroom doors.
There is no teen boy who does not do both of those and neither is generally a sign of asphyxiation, but of a normal hormones.
