I can't remember if I participated in this discussion last time it came up, so...I'll post anyway.
From the start of ME1 I was interested in Garrus, but at first it was simply platonic. He (and Wrex) became my permanent squad, and over the course of the game he became the character I looked forward to talking to the most. I liked talking to everyone...but with Garrus there was this eager anticipation that no-one else gave me. About halfway through the game I had a moment where I realised "Oh Em Gee...I think I'm in love!".
At that point I was already romancing Liara, but every playthrough since I've kept myself single and pretended that I was romancing Garrus.
@Mrs Vakarian - and everyone else who doesn't want a "Prince Charming" or "Knight in Shining armour" - you may be interested

I think the only useful thing I've posted was the turian art from Kasumi's mission.
