Its horrible how an act that used to always be fun and spontaneous suddenly becomes the whole entire focus of your relationship. DH and I have had a few of those occasions over the years of TTC, and while its not like it was a hardship for him, I do think DH felt like he was a bit of a performing monkey at times - especially when it got to the whole "no, we can't DTD now because its too close to O'ing and we need to wait", followed by the "yep, right NOW".

I think the secret is to try and make sure that for the rest of the time you try to make DTD as spontaneous, fun and relaxed as its always been for you both - easier said that done because if you're anything like me, that time after O'ing you're just so over the whole stress of getting everything right that you can't be bothered. FWIW, one of our daughters was conceived via a quicky in the shower and another on a month where we were having a break from TTC. Our latest on the other hand was conceived via pinpoint timing and hormone injections. When it is the right time try to keep the romance in it, rather than making it a military operation. Just because you're actively TTC doesn't mean that you can't still do the candles, music, romantic dinner leading up to it etc.

Good luck. It can be a very stressful time and difficult not to lose it a bit. I hope you get that magical BFP very soon.
