Sex in the third trimester, help!

So basically, sex is not fun right now. Certain positions hurt my round ligament, sometimes I feel like the baby is getting squished, and I get fatigued so fast! To make it better, I read that your labia can change during pregnancy, and mine have... They have gotten longer, plus I've gained some weight so it's like my clit freaking disappeared. I can't finish anymore, and when I do, it doesn't feel that great. I also struggle with my pH. pregnancy hormones change it too. I feel like I'm musky all the time. My husband can't tell but I feel straight disgusting. I'm so frustrated because I'm smelly, I have an ugly vagina, and I can't finish. Plus, I have more folds down there, which traps sweat and discharge. No one warned me about this side of pregnancy and I am so frustrated. Any tips or advice would help. I'm really just venting cause sex has been sucky.

P.S. I don't want to put the blame on my husband. It's not his fault. It's my body.
