Sorry - totally offline and give me the jeers for this but when I first saw Crashfrog's post containing the following:
It's a matter of scientific fact that a woman is more likely to contract an STD from her male partner than the reverse. Only one of those two can be pregnant...
I immediately (forgive me) exclaimed aloud in my mother's basement room equivalent:
Wow - getting pregnant is an STD!!!
Now I happen to think the ZPG people are correct, but this reaches into Jonathan Swift shorelines a tad.
...ok...back to your fascinating discussion......
