Okay this is new information to me😅 I know that using vaginal wash a lot is not good but I am actually a bit sceptical about the plain water being the cause I'm not a doctor or anything but I have been using bidet spray since my mama started potty training me and from that I honestly don't think this might be the problem. I would check with a specialist just to make sure there's no infection or something like that. And maybe ask about water cleaning for us too😂
I haven’t washed my self with the shower head in a week just letting the water rinse down as I shower (if that makes sense 😅) and no discharge or itchiness! I was just cleaning it way too much and it was washing away all the good bacteria
I think it can be possible if you are putting strong direct water pressure to deep clean. Ive always just slightly bent over under the shower head so it runs down my back into there and use my hands to wash around. But from the sounds of it, it may be worth you checking for thrush too!
