I'm guessing Jesse means "not safe for work" or in America "anything with boobs".
4 scenes to look out for :
- The couple murdered by the Experiment in Ep. 1
- Jade with Dougie in bed (Ep. 3 I think)
- Janey-E and Dougie/Coop (you only see Naomi Watts' back, though)
- Diane/Linda and Cooper/Richard in bed in Ep. 18.
