User blog comment:AdmMiller/What's so great about Tali? And why do most dislike Miranda?/@comment-743796-20100714125405

@ Harbinger265: I wouldn't assume that Tali is a virgin, as you seem to imply. As for Garrus, he did mention that he is more known as a playboy and/or hustler more than anything else not related to his duties. Regarding his "scene" with Shepard, he mentions that he has quite a bit of experience with female Turians, but femshep is the first human that he would attempt to romance.

As for Tali's face, you can make out slight outlines from outside the mask. It seems they are avian (like birds) in origin, as the eyes are wide and the facial outlines are thin. Not to go too off-topic here but Quarians look like the Chozo (the bird-like species that raised Samus in the Metroid series).
