Here are just a few of the messages that young people today are constantly exposed to:

• You're missing out if you don't have sex

• Marriage is out of date

• Casual sex is OK

• Sex is the goal of a night-out

• Sex is all about me and my satisfaction

• Sex can be experienced without consequences

• There are no rights and wrongs in relationships, just what we prefer

• Sex is a means of securing love

This book shows these things to be the half-truths and lies that they are, and points young people to what the Bible teaches. Singleness and marriage are shown to be God's gifts and 'going out' something that can be done in a God-honouring way. The temptations - pornography, masturbation, homosexuality and social networking - are discussed. There is practical pastoral help in a section 'What to do if you have made mistakes.'

The authors are the founders of Lovewise, a charity which seeks to help schools and youth groups by providing presentations on the subjects of marriage, sex and relationships from a Christian perspective.
