TTC-how involved is your male partner

My husband and I have been married for a year and a half and have been seriously trying to conceive since January 2016. I am older (will be 37 in November) so I definitely feel like my time is ticking away but I'm trying not to stress about it. My dilemma is how involved should I have my husband in the tracking process? He knows my fertile week is after my period ends but doesn't know for how many days. He knows that I test my urine with the ovulation sticks and asks me if I tested and what the results are. And we have agreed that if I am not pregnant by the end of this month we will start our first round of Clomid. I don't want our sex life to start to feel like a job or an obligation to him to where it's not enjoyable. I know when I start the Clomid the doctor is going to suggest sex every other day, or every third day so that his sperm has the best chances of travel but I don't really want to tell him no we can't have sex tonight if we're both in the mood.
