Sex is a chore and punishment 😰

Tiffany • Mom of four beautiful girls and married!!
I'm 29 weeks and I swear sex is a chore and punishment for me. My belly is so big and when my husband "tries" it I be ready to fight😂. Seriously I can't breathe and back hurt hell I don't even get an "urge" to even want to remotely have sex. It isn't him it's our unborn son . He balls up and has a fit when my husband tried. So my husband says it ok and just holds me but as his wife I want to "please" my husband 😰. I'm so happy he is understanding. We have four girls and this is our fifth and last yet first boy and I have NEVER been through this EVER! 
Seriously soon as I lay on my back I swear my baby be like: No!😡👊 STOP!👊👊👊😡 BACKUP😈😡👊👊👊 HELL NO👊 DONT EVEN GO THERE!✋ We tried different positions but no matter what my son "HAS to be the sex police 👮.  Hell I tried oral and I love "giving" but nooo😑 after all my life giving the "deep throat" all of a sudden I have gag reflexs that can stop a bullet😵.  Y'all care to share a story?
