I'll join you. DH and I are somewhere between trying to avoid and NTNP.
I have told him flat out that I am NTNP, but for his sake he isn't ready yet we will avoid my fertile times.
I'm Catholic, so we don't contracept or withdrawal or anything. If we have sex, it has to be real sex, all the way, no barriers or skipping the ending. We used to use withdrawal before I became Catholic, and I would never go back, it's so much more complete when you finish it the way it ought to be! (And much more chance of being blessed with a baby!) DH is not Catholic, but he doesn't insist on pulling out. I'm not making him keep it in there, you know? He's such a great husband.
So anyway, we use NFP to avoid, which is tough post partum, and causes some tension. Everytime we argue about it, he is all "we don't get to have sex because you are Catholic!" I just remind him that no, we could have all the sex we wanted if he wasn't so insistent upon avoiding pregnancy...
Anyway, he decided that he wanted to have sex on a "yellow" day, which we would normally avoid on. He made the conscious choice to, we talked about it and I was sure he wasn't just caught up in the heat of the moment...so that gets me thinking, perhaps he could go all out NTNP soon?
Also, I got a peak 2.5 days after that "yellow/high fertility" day...and got ovulation cramps 3.5 days later...technically your chances of getting pregnant with sex 4 days pre-o is kind of low, but 3 days pre-o are much better....So now I'm kinda TTW'ing.
But the entire point, I hope, by DH choosing to DTD on a high fertility day, that perhaps he would be open to saying screw the tests and green/yellow/red days, and just NTNP all the time and see what happens...I can only hope!
