Sex with S/O

Anyone else's S/O not even attempting to have sex with them? You'd think he was pregnant. My sex drive is low for sure, but it still makes me feel shitty that he doesn't even attempt it. I even offered sex a couple times and he took no interest. It makes me feel ugly and gross and paranoid. He did this when I was pregnant with our son, but not until I was like 25-30 weeks or so. I'm not even 15 weeks yet this time. I just want to know if I'm alone in this. 😞
