Partner says he’s disgusted with me.

I found out I have a double vagina and uterus and cervix. I didn’t even know. They said I had a possible duplicated uterus after I had an ultrasound which was later confirmed by an mri. I told my SO and he was like wtf. When we had sex he keeps going soft he said he just couldn’t get the image out of his mind and said that he thinks it’s kind of disgusting to have two vaginas and he wouldn’t be able to eat me out anymore without gagging. I got upset and almost cried and he said what if I had two dicks you would feel the same way I said no it wouldn’t change anything then he was quiet after. I wish I never told him.
