Well you were saying that the only answer was of a biological nature, I was pointing out that while it probably factors one way or an other it's a bit presumptuous to say that it's the only reason. In particular your example: "Many women would be uncomfortable or refuse to have a male caregiver help bathe or dress them." I think there's a massive cultural component to this, rather than some innate behavior. And the fact that there are many male gynecologists show that many women aren't that picky with their intimacy...
