Angelina
Angelina a girl who is so close to suicide usually has a rather broken family relationship
In reality it is unlikely that the wearing of the belt, alone can, lead to a suicide attempt. (I concede it to you)
But if the wearing of the belt comes at a time when the girl feels very bad (breakup with boyfriend, school failure, does not feel good in his body ...) and well in this case the wearing of the belt that would now prevent him from masturbating (by depriving her of the only moment of happiness to which she could still hang on) this can unfortunately lead to a desperate act.
Once again, repressing an individual's sexuality is not harmless on the psychological and emotional level.
