This is a good position, and it doesn't mean that the man is weak or the woman is dominant.
However it can occasionally be dangerous for the man, as the penis can be "fractured". Although there are no bones, a force to the erect penis can damage the erectile tissue or even damage the urethra. This can happen if the woman bounced too high, the penis slips out, and she comes down upon it at a slightly different angle.
