The dynamics of the gender fluid, are extremely insufficiently researched. In fact, the Wikipedia page for the gender fluid of people with uteruses (who represent approximately half the human population), is in such a sorry state in terms of academical knowledge content, as to contain this, embarrassing paragraph:

Whether the fluid is secreted by the Skene’s gland through and around the urethra has also been a topic of discussion; while the exact source and nature of the fluid remains controversial among medical professionals, and are related to doubts over the existence of the G-spot,[9][10][8] there is substantial evidence that the Skene’s gland is the source of female ejaculation.[1][8] The function of female ejaculation, however, remains unclear.[8]

The reasons for this disgrace are sociopolitical, therefore, curious person, since this page is painfully incomplete, you can help by contributing!

Conduct research, collect knowledge about the nature of gender fluid and how it performs in various tests, and share with your peers and the world!
