I saw a witness couple locked in inter-course during a assembly prayer !
Just kidding, but really why would they put a stop to this since it might actually show that love could be found within the organization.
But then again since most single adults have a difficult time finding appropriate mates within this religion, this
might actually create inner jealousy within the singles and may even stir up sexual tension.
if you want to see and observe a large group of sexually up tight and tense people go to an assembly and look around.
