Dr Julian Lewis: The hon. Lady [Oona King] knows that I much admire her views on many subjects but I disagree with her on this one. She has used anecdotal evidence, so I remind the House of something that I said when the matter was last before us. The only known gay boy in my secondary school – he was mercilessly teased and bullied and I felt great sympathy for him – told me that he started on the road to being homosexual when he was under-age and was interfered with by an older youth.
