Before the 1960s, sex before marriage was frowned upon and pornography was difficult to get hold of. We are now much freer to do what we like – there has been a ‘sexual revolution’. This must be a good thing, right?

Wrong, argues Louise Perry. These changes have had many negative consequences, especially for girls and women. The main winners from a world of rough sex, hook-ups and freely available porn are a tiny minority of rich and powerful men. Women have been forced to adapt to these changes in ways that often harm them.

Louise Perry carefully guides readers through the difficulties of sex in the 21st century. Her advice will be invaluable to all young women and men who may be feeling lost in a world where ‘doing it’ can sometimes seem dangerous or confusing.
