English: Boyflux/Manflux/Mascflux is a gender under the genderflux umbrella describing someone whos male gender fluctuates in intensity. This typically involves feeling strongly masculine sometimes and weakly masculine at other times. Boyflux people can fluctuate from feeling completely without gender to completely masculine or male. In between those extremes, one may feel slightly masculine, to half masculine, to mostly masculine—but not fully—, or any other amount of masculinity. Some people may move smoothly between intensities while others may quickly jump between intensities.
