The Sexual Compatibility Project


We are now recruiting couples for a follow-up study on perceptions of sexual preferences.

Researchers at Western University are looking for participants for a large-scale study on relationship experiences. Specifically, we are looking to recruit couples to learn about their perceptions pertaining to both their own and their partner’s sexual preferences.

Note: People who are seeing someone very casually are still eligible for the study. Individuals who are in consensual non-monogamous relationships are also still eligible for the study.

This study is part of a series of studies to further investigate sexual similarity, sexual complementarity, and perceptual accuracy of sexual preferences, we hope that they will greatly improve our understanding of how people’s perceptions of sexual preferences (i.e., sexual compatibility) may be associated with sexual satisfaction and relationship quality.

To be eligible to participate, you and your partner must meet the following criteria:

  1. You must currently be a couple (e.g., dating, in a relationship (i.e., romantically attached), or in a consensual non-monogamous relationship).

  2. You must be at least 18 years of age.

  3. Fluent in English

What the study entails. If you agree to participate, you and your partner will be asked to complete two separate and identical confidential online surveys. The survey will take approximately 60 minutes to complete, and you will both be asked a series of questions about yourselves, your partners, your relationship with your partner, and your sexual preferences. Participants should complete the surveys on their own (i.e., not in the presence of their partners or others) as this will provide greater privacy and confidentiality. Surveys will be sent to you via email using Qualtrics’ participant mailing list feature.

Compensation. All compensation will be emailed to participants as Amazon gift cards. Participation in the research study will grant you entry to a draw for one of four $25.00 CAD/USD Amazon Gift Cards. Couples who both respond to the study will both be granted a bonus entry – for a total of two each. You are not required to complete all the questions to be eligible for the gift card draw. You can withdraw from the survey, at any time, by simply exiting your browser window. Withdrawing from the survey will not jeopardize your survey compensation.

Contact Us. If you have any questions about the study, your primary contact is Devinder Khera (, or you can email the Principal Investigator, Dr. Samantha Joel at
