If I'm wrong, someone correct me, but I doubt Giant (or anyone else) makes women-specific bikes with the team paint jobs. I think they used to designate their women's bikes with a W.

I ride a medium (50 cm) Giant women's road bike. I borrowed the equivalent unisex model (a few years older, but same measured size and whatnot), and I was way stretched out. I had a fair bit of back and shoulder pain from a 12-mile ride. (For reference, I'm 5' 6.5") Short-reach shifters would have helped in that situation, but not much.
You can't really gauge much, I'm starting to find, from really short rides, unless something is really wrong.

I'd be intimidated by something that aggressive, if I were a new rider. Heck, I'm still a bit intimidated by it. It's pretty, though.
