SC: Yes, of course, it was an analogy. Most literature states that the missionary position (woman lying flat on her back, man on top) is not enjoyable for the woman, and women cannot usually have an orgasm in that position. In my experience, and my midwife's experience, this is simply untrue, despite all the "reasons" that it should be true. Similarly, most natural birth literature comes out against any position that puts pressure on the sacrum, including semi-reclining; but again, the real-life experience of my births and my midwife's many years of experience comes out that it can be a fine position.
None of this is to say that the missionary position is semi-reclining. :-) (Did I have you wondering if you were doing it wrong?
