Painful sex..

Brit

I have severe endometriosis and sex is horribly painful and my poor husband is getting understandably frustrated.. I have next to no sex drive because it hurts so much.. Any ladies here have any advice to make it less painful? I should add it isn’t the penetration itself, well lubricated and all that, it’s my abdomen that physically hurts and makes me want to vomit after.. Doctors have been no help..
