Epstein Sexual Orientation Inventory (ESOI) v. 3.0, © 2006-2019, Dr. Robert Epstein  

You are about to take the Epstein Sexual Orientation Inventory (ESOI), a test of sexual orientation designed by Dr. Robert Epstein, one of America's most distinguished research psychologists (follow on Twitter at @DrREpstein). The test has been empirically validated with a sample of more than 600,000 people in 219 countries and territories.

Although many people believe that everyone is either "straight" (heterosexual) or "gay" (homosexual), sexual orientation actually exists on a continuum. This test will show you where you are on the Sexual Orientation Continuum, and it will also calculate your Sexual Orientation Range, an estimate of how much flexibility you have in expressing your sexual orientation.

If you are conducting research and would like to collect raw data for a group that is taking this test - for a business, research study, classroom activity, or other purpose - please see our Group Testing Instructions.

The test is also available in Simplified Chinese, Traditional Chinese, Arabic, Italian, Malay, French, Spanish, German, Hungarian, Dutch, Korean, and Japanese.

Before we get to the test itself, we'll ask you a few basic questions about yourself. Demographic information is being collected for research purposes only and will be kept strictly confidential.

To make sure the scoring is accurate, be sure to fill in all the blanks!
