my pussy tastes different

my boyfriend used to eat me out all the time then he stopped. its been about 2-3 months since hes gone down. I just asked him why he doesnt do it anymore and he said my pussy taste different then what it did. He said it used to taste good but now its weird. its not bad but different then what it was. I haven't changed what and how I eat or my physical activity level and I clean it the same way as before so I dont know. Is there anything I could do to help?
