No feeling ever to poop

I’m hoping someone will be able to help. I’m 52. Have constipation issues for years. Last year and half have been frustrating. I never feel the urge to poop. I would have to force a fart. Which farts barely happen. Only way I feel the urge to poop is taking Dulcolax. I’ve tried all the suggestions of doctors, researched. Suppositories. The latest suggestion: the doctor said not to take any dulcolax. See how long I could go without popping. I’m on day 10. Nothing. Except my skin is starting to flare up with acne from the toxins. When I do use the Dulcolax, it’s like opening a flood gate. I need to stay home for the morning because the poop comes out as fluid with some loose stool.
I had X-rays and stool sample done. All is well. I’m waiting for a cat scan in November…which was asked for in January… if anyone could share their knowledge or story, I would be so greatful. Thank you
