Fetishizing for a male audience? That seems rather male-centric in and of itself to even say. Just because some guys take interest in something doesn't mean it's exclusively for this vague notion of a male audience, as if guys are somehow not individuals foremost just like us girls. Also, normal relationship? Who are you or any particular person to even decide what is or isn't normal? And what does that as a value judgement even mean? What if a relationship isn't normal to you? Does that mean it is somehow less valid? Criticizing something for not being what you find normal comes off as rather judgmental and intolerant. Depending on the context, even imperialistic.
How about this, anyone is open to take interest in such relationship depictions, men or women, regardless of their sexual orientation, or even disinterest for that matter. Vague stereotypes based on speculation and rumor spreading being super imposed onto demographics be damned. Whether or not it's a "normal" relationship to me or anyone else seems completely unimportant and valueless to even take in consideration. Regardless, such pairings aren't exclusively for or owned by contrived ideas of the "male audience" or the "male gaze." I for one tend to enjoy such relationship depictions while not falling into either overly generalizing term.
If it isn't for you, that's perfectly fine, but I see such notions like what you stated as nothing more than veiled attempts at attacking such depictions from even existing, mispresenting their audience as an imagined absolute with a super assuming generalization of what that fake absolute sees life as through their perspective. Completely absurd and equally absurd if applied for any other imagined absolute as well. Men and women both are the audience and neither are a hivemind regardless of what percentage happens to be made up of either demographic at any singular specific point in time. Both are made up of individuals who think for their selves. Truly, the individual is the most oppressed minority in human existence.
