no, of course not. however, it is well-known that at certain ages and in certain social classes women/girls are more conformist than men/boys, and that includes following the linguistic rules laid down by the self-appointed pedantic "experts", so that a man/boy who follows them will be seen as effeminate. by th way, what u call a reasonable command of the language is mostly ignorant kowtowing to artificial rules made up by people wholly ignorant of how languages work and evolve.
