Most women don't orgasm from intercourse alone, they need clitoral stimulation So in that respect, your first girlfriend is completely normal. Expecting her to do something extra may just be putting unnecessary pressure on her and probably isn't that good an idea. If she's happy with it, I wouldn't force it.
As for the second girlfriend, that is also very common. Women are very different and you probably shouldn't worry about trying to make each more like the other. Enjoy their differences!
