Yeah Jade and Tommy in TeenBBUK there was some unmistakable thrusting action going on under that duvet

, The date of that article you posted (4th June 2004) also suggests this was around that scene with Stuart and Michelle first got frisky in bed (And Dan wakes up for a moment in the bed next to and registers what he is looking at then goes back to sleep lol).
I'm up to Week 4 now, Jason managing (or doing a poor job of) his needs and 'dedicating his w@nk' to Vanessa and commenting about women working out being a turn on in plain earshot of her doing weights have been some forward and frank discussions lol. Another update thoughts post in a bit.
