My obsession is causing issues

Ladies- I don't know what to do. My bf and I rarely fight. Last night he got so frustrated with me because he said I was being too pushy about having sex. He said it felt like a ticking clock all the time :/ I don't want him to feel like that, but at the same time I went to bed upset because we didn't BD. I just don't think he understands how much happier I would be if I just got that BFP. I don't want to change our relationship though... Tips? Advice?
