I think I can go one better than David Conroy (Letters, 1 April) in surviving the Mary Whitehouse experience. In the 1970s, I was part of the small team in the Department of Health and Social Security responsible for policy on sexually transmitted diseases (STDs).
Part of my job was to reply to letters. They could be very wide-ranging, and we devised a stock reply, basically telling the correspondent where they could find information on STDs and, if need be, treatment.
