TW/ mention of bulimia.

I’m wondering how to get rid of a bad gag reflex? i had bulimia in my teens and then had an immune system issue for a couple years so i was sick with flu and bugs for ages. now i IMMEDIATELY vomit when anything touches the back of my tongue. barely even the back to be honest like i can’t even wash my tongue without vomiting. i’m really into blowjobs and have a huge oral fixation but i’m struggling. is there any way of getting rid of it?

btw i’ve tried like practice and exposure and stuff i did it every night for weeks ive tried with toys and my toothbrush and fingers but after i try once even looking at whatever it was i start badly gagging and my tongue cramps. thansk sm for any advice
