Umm...may I ask why you'd even consider machines?
The benefits you get from "lifting like a guy" aside from the respect you'd garner from being around guys and training, is insurmountable. There's no comparison to the benefits from weights to machines.
I train over 35 women, all of different walks and ages, and they lift like guys, but all look sculpted at one degree to another. That being said, they squat, they deadlift, they bench and they aren't "bulky" like guys.
The intimidation you probably feel is within yourself; my advice? Get over it. You'll thank me later, and probably within weeks. If you want to supply you with a basic weight training workout, I'd be more than happy.
