28 weeks tomorrow and DYING

I am so blessed to be having my third child (4th, including my angel son) but GOOD LORD. This is ridiculous. this is THE BEST pregnancy I have ever had, but I am so miserable on the sex front. I'm such a sexual person and my husband is FINALLY worshiping my pregnancy body for the first time ever and I CAN'T HAVE SEX. I mean, of course i do, but this baby is so big and I'm stretching so much more than I ever have and i can't even have sex for more than 20 minutes without having horrible Braxton Hicks that leave me breathless. My feet and tummy cramp if i take top, the baby gets horrible squished if I'm on bottom, my husband is bored of the spooning position, and doggie is getting old. I'm SO UPSET. and after we're done, my vagina feels like its going to literally fall out from the immense pressure and the BH contractions make it impossible to make him feel like he did an incredible job because he has to take care of me an and apologize for hurting me. 😭😭😭 I just want my sex life and my body back. My hips are spreading so far that I can't get up from bed in the morning for at least 30 minutes, so you can imagine what its like straddling my 6'4" 230 husband every night. I NEED HELP. I NEED WORKOUTS OR REMEDIES OR SOME SORT OF HOPE ITS NOT ONLY GOING TO GET WORSE FROM HERE.
