Pristrosexual is when one may gain sexual attraction at any pace but they must tell the other their own feelings before the other reciprocates the emotions, or else all previous sexual attraction will be lost. An example of this is: A is attracted to B and C. B confesses that they also have the same attraction to A that A felt for B, but A no longer has that attraction to B because B confirmed their reciprocated attraction to A before A stated their attraction to B. Since A is only attracted to C now, A tells C that they are attracted to C and C reciprocates the feelings that A is having towards them. A still experiences attraction to C but no longer feels attraction to B.
This term falls under the asexual spectrum and can be combined with other terms. The romantic counterpart is pristroromantic.
Etymology
