Kroy Biermann says he has no desire to call off his divorce from Kim Zolciak despite having sex a couple weeks ago ... claiming banging her doesn't mean he's changed his mind.
The retired NFL player just fired back at his estranged wife ... making it clear he is still gung-ho about divorcing her, selling their Georgia mansion and moving somewhere else with their kids.
In new legal docs, obtained by TMZ, Kroy says the fact he had sex with Kim "does not indicate a desire to reconcile" and he "remains steadfast in his desire to divorce" her.
