Young people are likely to still be developing their sexual identity. The outcome of sexual identity formation may not always be finite. Some people may identify their sexual identity differently at different stages of the lifespan. This may be by choice or they may have been unable to fully develop or express their sexual identity at a younger age.

The process of disclosure of sexual identity (for example, a young person who is same sex attracted coming out to their family) impacts upon sexual identity formation, particularly for young people. Disclosure can occur in a variety of contexts, including educational and health care settings and can often be a stressful experience for young people.

This reading discusses some Australian same sex attracted young people's experiences.
