It happens a lot, these days.
Anyone who teaches 16 - 19 year olds will tell you - sex is a great game to play a lot of.
I read a piece way back when (probably Mackie in the mid 80s) that it might be one of those risky shift/social comparison theory behaviours - your peer group does sex, so to fit in you show them how far you'll do sex to fit right in/become a leader of the group.
Given the difference between my youth and today's teens and their ways and means of socialising it makes more sense that risky shifting is more extreme these days.
So a knob such as Smith is, therefore, a great social risk shifter/challenger, he runs these events, promotes them as normal, identifies himself and business with such behaviours. He'll take the backlash cos it is such good fun - and earns him a fortune!
