Changing the ph level

Rozu🦊

Is there a way to change like the vagina’s ph level? My boyfriend stopped eating me out cause it gave him heart burn(he also says he cant take tums) and now he feels bad about it...so can i make my vag less acidic? Or is there other things that can help with this? Like I discovered mberry tablets or would flavored lube help?? I just wanna get eaten more 😫😫.

Edit: i should Also mention that he does have acid reflux and heart burn problems in general
