Is it Thrush? VA mimics that itchiness, 4 me thrush irritation is too high up to scratch

and VA is like razor blades up there

Use YES on the end of your finger, inserting gently? Lay quietly with a good book for 20 mins. ;-). I don't worry about disposal, it's how things are burnt or recycled that is the important issue in the UK. I put my applicators into plastic waste, washed thoroughly of course.
Maybe buy some LIVE yoghurt, eaten and applied. It cleanses the whole digestive tract and will encourage good bacteria. Thrush/candida lives in the back passage so toilet hygiene is important. It likes warm areas in which to grow. Applied: lots of yoghurt on the finger or on a tampon, as high as possible to ease that itch. Keeping tubs separate of course ;-).
