The whole game is designed so that anyone that resembles a female to
throw herself at male Shepard.
Kelly, Shiala, Samara's loyalty quest and Morinth, Jacob about Miranda
deserving better - works perfectly for male Shepard, Tali rambling
around how she misses Shepard and so on.
What does female Shepard get? The only one that acknowledges the fact
that Shepard is a female outside of LI is Aria at some point saying
something like "find yourself a young man".
And what is Bioware planning? Kasumi - because male Shepard can never
have enough women around him.
It is annoying and frustrating to be left out.
And just for the sake of it and because male Shepard could never have
any type of competition Bioware decided that Thane is dying.
