I am all for sharing EVERYTHING in a relationship - however, sometimes it truely is better to limit some info to 'need to know' basis or 'requests to know' basis (ie, he asks you). My DH is fully supportive of TTC, ans he has been aware each time that I am charting and using OPK's. Occaisionally he will ask me about it all, but I know he sometimes feels ripped off, like I am just 'using' him to get pregnant. I know it is illogical - but think about it from his perspective. You may only have been interested in DTD half as much (or even less) prior to TTC, and now it has increased NOT because you want HIM; but because you 'need' his sperm. If in some alternate universe, he only 'seemed' to want to have sex with you as a purely machenic function (ie, TTC) but showed much less interest any other time: you would likely be feeling a little sensitive to say the least. Trying to keep the romance whilst TTC is hard work - but the last thing you want is for it to become a 'chore'. So restricting the depth of information isn't a bad thing, it is just that sometimes a little mystery goes a long way in a relationship. I mean is it really that imperative that HE actually knows every detail about your cycle??? Or is he perfectly able to fullfill his role without knowing you have EWCM and a temp of 37.4????
