Just a thought I had, honestly I hesitate to comment on things especially if only girls are talking but I was a student nurse for two years amung other medical jobs I've had so I often feel I know more about women than some of the women do. But I don't want to be the guy that "intrudes" as as many pointed out there are a lot of not so Christian people on here.  But my wife and I enjoy working together to not conceive (and I know when her period is coming so I can get her chocolates and ice cream ;). What are your thoughts?
