hi im having a brazillian done next week, im not sure how long the hair should be as ive had problems shaving so decided to wait now there is really long down there ( well i aint shaved for about 1 month so its like a forest lol ) i hate so cant wait but now im worried as last time she said its well to long but wouldnt cut it as i suffer from hairs all over ( bum) i dont want to be to long as it would hurt more i have a electric shaver which i could use to trim but how far should i
