As part of a season marking the 40th anniversary of the Homosexual Reform Act, How Gay Sex Changed the World charts the incredible journey of gay men over the last four decades, to far wider social acceptance and a greater sexual entitlement then ever before.

As gay men have grown more confident, the gay sexual revolution has been at the forefront of a wider movement towards sexual freedom and expression. Contributors include David Furnish, Simon Callow, Jimmy Somerville, Peter Tatchell, James Dreyfus, Matthew Parris, Brian Sewell, Andy Bell and Ian “H” Watkins.
