Although I like your train of thought, Curtis beware of the term "sucker f'ed"! She ultimately has the last say in these matters. Don't get suckered into the "practice sessions".Hmmm... there could be a down side if you're too obvious. As a delaying tactic, you could try to convince her you need more practice before you actually get her pregnant. Call it "pre-season training".
HAHA now that's funny!its not like its going to be your last wife anyways right?
If your looking for me, I will be sleeping with the dogs tonight
