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. The test has been empirically validated with a sample of nearly 18,000 people in more than 40 countries.
Although most people believe that virtually 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 give you an estimate of how much flexibility you have in expressing your sexual orientation.
NEW! As of December 1st, 2012, the test includes a new, more accurate measure of sexual orientation flexibility, as well as a measure of overall sex drive.
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
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.
