hi undercover
hmm, it's a really tough one, that. On the one hand, your DP is right -babies should, ideally, be made in a happy, spontaneous, lustful, blah blah blah manner
Of course, that isn't really how it works a lot of the time, and I can certainly sympathise with the feeling that, now you've made up your mind about TTC, you want to proactively make sure something happens now!!
The way I see it, you have a few options:
1, Don't tell him when you're ov'ing. I assume you must have been talking about it since he accused you of only being in the mood because of that. Some girls swear by not telling their partners any details about ovulating, temps, CM etc, in order to keep sex from becoming a chore.
2, Agree to have sex every second day, no matter what. Depending on libido/life situation this might not be very convenient. But there's an article in a recent Guardian that pretty much gives this advice
3, Talk it through and agree that, yes, you really are TTC and you understand what that means. Sounds simple, but there's something so big and scary about deciding to try for a baby that it's almost easier to just do the 'let's see what happens'. Especially for men I think. Me and DP were like this at first, but after a few months we sat down and pretty much agreed that, yes, we want this to happen. DP knows this means he has to 'perform' at certain times in the month We make little jokes about it, and also make it very clear to eachother how much we enjoy what is now referred to as 'pointless sex' as well...
Best of luck to you and hope you won't have to worry about this for too long!
