Sex is getting interesting...

I'm almost 31 weeks and sex is getting difficult! I feel like a dead fish sometimes. Like I can't move! Doggy style which is the easiest is painful at times & tonight my husband went soft because he swears he felt the baby kick when he was inside me 😂 then felt me get wetter and thought I started bleeding and made me go check. This is the first time he's ever had any qualms during sex while I've been pregnant. I officially feel like a  beached whale 🐳 if anybody can give me position suggestions for pregnancy please do ! I need to spice it up while also feeling comfortable
