When you are hurt in sex, in a way that does not cause extreme pain but just pure arousal, it builds your emotions that you can no longer handle it-and you are merely waiting for the peak where it is so painful and when it subsides, it is almost euphoric. There is a very thin fine line between pain and pleasure-both provide some sense of excitement, an ambush of extreme emotions until you can no longer handle either. It is widely practiced in the BDSM gay community, especially in bondage porn where the pain is part of the pleasure. Especially in gay porn, where it is all just men and their utter need to prove they are strong. But don't you know that hazing is also being practiced in sex? Yes, hazing does not only provide loyalty pains but also a pleasure. It is a symbol of their bromance or loyalty to the team. Hazing is a common practice in fraternities.
