Why can’t men seem to grasp the concept 😡

Why can’t men seem to grasp the concept of the “fertile window” and ovulation day?!? 😡😡😡

My hubby seems to think we can have sex anytime to get pregnant since others fall pregnant by accident all the time. We get it in sometimes during the fertile window but he’s pissed me off a few times after a positive opk being too “tired” or “stressed” for sex.... Then he’ll try to have sex 2 days later like it’s a big deal and I’m like “it’s over!! You missed it!”

Anyone else?
