imho if all genderswapped guy MUST BE paired with another girl because he was straight before , why even make h/er a TS girl to begin with? might as well make full blown yuri from the go instead of some half-baked TS yuri.
guy get TSed and then without problem/conflict/hesitation/etc get on with a girl? bad writing

and please before you grab a pitchfork , remember after all is said and done, this whole TS girl phenomenon DOESNT exist. No recorded event about guy/girl get their sexes swapped by higher forces/being/etc ever took place so whatever end ship the author want to take is valid. THE real question is just how those author can make the ride to end goal enjoyable, not about muh supposed yuri/yaoi argument.
