The idea that the ability to "properly" play a specific gender is exclusive to that gender, and the people that list this in their search threads. If these people are so concerned with the quality of their partner's characterization, shouldn't they search for skilled writers, and not a specific gender of writer? I've encountered plenty of women who can't play anything other than their self-insert, or mary-sue, and plenty of men who can't play anything than their generic, cool guy character. It makes no sense to me, and I think it just boils down to wanting what makes them happy in their pants. The thing is that they don't have the guts to be honest with themselves, and others, to flat out state that they're looking for a specific gender, because it's more arousing. I get if it's a comfort thing, but why not just say so? The bullshitty excuse drives me up a wall; I don't even have to be interested in role-playing with the person.
