What does FTM mean on Grindr?

Could you possibly clarify for me the meaning of the abbreviation "FTM" when encountered on Grindr? I've noticed it several times but am rather puzzled as to its specific significance within the context of the platform. Would it perhaps refer to a particular category, status, or some sort of identification? Or could it be slang or shorthand for something else entirely? I'm quite curious to understand its usage and the reasons behind it. Thank you for any assistance you can provide in deciphering this mystery abbreviation.
