How to make yourself taste better down there?

Being eaten out makes me anxious I won’t taste good. And I know taste can vary from time to time. My boyfriend finally did it after I let him (my first time) and then did it a second time that night. But we haven’t since. He didn’t seem bothered. I know I don’t smell. I keep it clean and fresh. He said he enjoys it. How do I make sure it tastes good? I’ve heard take chlorophyll but not sure why or what does. I don’t expect it to taste like cake but don’t want it tasting bad. I use regular soap and water, nothing scented, nothing that will throw off pH, and don’t douche.
