For those worried about their partner's, erm, private pursuits, London's Metropolitan University host this open debate on the impact of pornography on relationships. Chaired by writer and broadcaster David Aaronovitch, the talk also features Scarlet magazine editor Sarah Hedley, psychologist Susan Quilliam, researcher Mark Limmer and LMU's Dr Maddy Coy. Together, they take into account an individual's level of porn access, age and amount of usage in their analysis of lustful leisure activities. The enlightening and provocative discussion may leave you hot and bothered — or perhaps just bothered.
