Discussing Ovulation with your Spouse

Jacquelynn • Paramedic Student, wife of an amazing man, mama to 2 beauties, and trying for baby #3
So my husband and I are trying to conceive baby number 3, and every time I bring up the fact I'm ovulating, he becomes really hypersensitive and asks if the only reason I want to have sex is just to get pregnant, when it's both a baby and my want to have sex. 
Shy of not saying when I'm ovulating, I don't know how to discuss this with him. The fact that I want to be intimate with him, and make a baby... Why does it have to be one or the other? 
Does anyone else have this problem? 😕
