Sex while 7 months pregnant‼️🙄

I need advice or tips to on how to keep my sex life active , I mean my bd lately has been so into the mood and I have too ! But the problem is that since my belly is so big I can’t seem to find a comfortable position, which is I either ride him I start to get this pain on my side of my belly and is uncomfortable when I’m moving, missionary it feels like if he is putting to much weight on me even tho he isn’t and it makes me ran out of breath ☹️, doggy position is the same thing I get this pain on the lower side of my belly and is super uncomfortable. I don’t want him to end up not wanting sex with me cause of this little problems, but I can’t seem to find nothing to make me feel good when it goes down ☹️. Any tips lady’s it’ll be so much appreciated it 💕 .
