Re priest in Brisbane.
I get a real tickle out of these little episodes. Mutual, non coercive sex play between two persons is doing no more harm than taking a kid for a boat ride or a camping trip.
It is largely the attitudes of the church that made a mutually pleasant activity sinful.
For instance, Take 11 highly sexed boys, Form them into a circle (in the parlance of football called a huddle). Tell them to go out and stop 11 other boys from accomplishing a goal by slamming into them with all their might. Injuries are common in the game. The boys get a certain amount of pleasure out of it. Successful coaches are rewarded.
Take the same 11 boys , form them into a huddle. Announce a "circle jerk" contest. Nobody hurt and the boys get a certain amount of pleasure out of it. But the coach will likely be severely castigated.
Talk about being "hoist by your own petard"

Go figure!!!
