I would hope in our community we'd be well informed about genital anatomy. All fetuses are female to begin with; everyone started with the same vaginal and labia tissue when the fetus's organs were first formed. It's only subsequent hormonal switches that cause male anatomy to develop, the fusing of the fetal vagina into that line you saw, and the fusing of the labia to form a scrotum. If this is evidence of intersex, then hell,
all males are intersex!
Maybe the estrogen reawakens a faint cellular memory in that line where the fetal vaginal opening used to be, as if it yearns to reopen to its original state.
It's like the doors of Moria in
The Lord of the Rings-- at first they were shut so tightly that no crack between them could be seen-- but once the magic word was spoken--
QuoteThen silently a great doorway was outlined, though not a crack or joint had been visible before. Slowly it divided in the middle and swung outwards inch by inch, until both doors lay back against the wall.
Makes quite a metaphor for SRS, eh...
