Resist the urge to conform! You have something to offer the world as your unique self, and no one can ever see that if you hide it. Still, these shenanigans often tempt people into putting up a front in order to conform. There is nothing wrong with being masculine or feminine, whatever your orientation may be. On the flip side, I've also seen masculine guys being shamed lightly and assumed to be 'faking it' (as if gay guys are inherently feminine or something, and coming off as straight or masculine is automatically phony).
I've seen femme gay guys trying to act more 'butch' in order to attract guys who only want to date masculine men, and I've seen a lot of guys shaming more feminine gay men and implying that they are 'acting' feminine (as if it doesn't come naturally).
