whats it like finding out definitely that your dad's having as much sex as you, if not more? 
the woman's 39, probably her only chance for a baby. just a shame that you're so much older than it.
of course, you'll be feeling a wee bit jealous too, i'd imagine. hell, i know i would..
*hugs* congrats, though, you might end up with a baby brother :D and who knows, it might even make you consider settling down and having bairns of your own
