MPS — Full Definition and Meaning

Member of Preferred Sex is a gender-neutral abbreviation used in the Rice Purity Test to make romantic and physical intimacy questions inclusive for all sexual orientations.

Member — a person (one individual)

of Preferred — that you prefer, are attracted to, or are romantically interested in

Sex — gender or sex, referring to the gender you are attracted to

Put together: MPS refers to any person you are attracted to, regardless of what gender they are or what gender you are. A straight woman's MPS is a man. A gay man's MPS is a man. A bisexual person's MPS is whoever they are attracted to in a given situation. A non-binary person's MPS is whoever they are attracted to. The term was chosen specifically so that the question works for all users without modification.

How to use it: When you see MPS in a question, mentally replace it with 'a person I am attracted to' or 'my partner / the person I like.' That is the intended reading every time.

How to Answer MPS Questions — Practical Guide

Step 1 — Replace MPS With 'A Person I Am Attracted To'

Reread the question with that substitution. Ask yourself: has this activity happened with someone I find romantically or physically attractive? If yes, check the box. If no, leave it unchecked.

Step 2 — If You Are LGBTQ+

The test works identically for all sexual orientations. MPS simply means whoever you are attracted to. A gay man answering 'held hands romantically with a MPS' should think of a man he has held hands with romantically. The term was designed specifically so that no user needs to mentally translate questions based on their orientation.

Step 3 — If You Are Unsure Whether Something Counts

A general principle applies: if you are genuinely unsure whether an experience qualifies, it probably means the experience either did not happen in the way the question describes, or you are overthinking the interpretation. Answer based on your honest first instinct.

Step 4 — What If You Have Never Had a MPS?

If you have not had any romantic or physical experiences with anyone you are attracted to, the answer to all MPS questions is no. Check nothing. Your score in those categories will reflect that.

Why Does the Test Use MPS Instead of 'Partner' or 'Person'?

The original 1924 Rice Purity Test was written only for female students at Rice University. Its questions used gendered language — referring to male partners explicitly. When the test was revised for a broader online audience, the challenge was how to make the questions apply to everyone without rewriting every question from scratch.

MPS solved that problem efficiently. It is a single abbreviation that makes any question about romantic or physical interaction automatically apply to straight, gay, bisexual, and any other orientation. The term 'partner' implies a committed relationship — which many test questions explicitly do not require. 'MPS' preserves the romantic or sexual framing while removing the gender assumption.

Today the abbreviation feels dated to many users — which is precisely why thousands of people search for it each month.
