Ex-sextation

The feeling or thought that you will resume your old sex life with an ex with no regard for you present life or anyone in it.

Ex-sextation- I recently had seen my ex and acted on unrealistic ex-sextaion she was discussed.
My old partner had ex-sextaions that made me sure that leaving him was the right choice.
My ex-sextaions left me feeling lonely because she was over our last relationship what a bitch!
