This topic came up at least once before in the past, and at that time, after reading several posts from guys, I decided to see if it might work for women, too.
Granted, we're at a very distinct disadvantage, since we have to bend about 6-9" farther to reach the sweet spot. But I'm slim, lithe, and very flexible, and my boobs are small enough that they don't get in the way. So, I sat down on my bed and gave it a try.
I didn't even come close, and I could get no closer than about 8" away.
A life lesson...
