This documentary from Family Watch International is a very helpful introduction to understanding male same-sex attraction. It argues that no one is "born gay" and that many people with unwanted same-sex attraction have been able to change.

In 30 minutes, it packs in research data, interviews with top experts in the field, and powerful testimonials from four men who speak honestly, openly and compelling about what it was like for them to develop same-sex attraction and live the homosexual lifestyle.
