Postorientation or Isterosexual is an experience similar to postgender, but for one's orientation. It is a feeling that one’s identity has been heavily influenced and shaped by an orientation that one no longer experiences. For example, a postlesbian no longer identifies as lesbian but still feels a connection to that label or has been shaped by it in some way.

Istero comes from the Greek υστερο, meaning "post-" or "after".
