Do you have any recommended places for hair removal? A handsome hair-removal technician

Question: For removing hair on the butt, do you have to kneel and lie face down? I'm a 'top' (鐵1); I honestly feel I can't do that position — it's very embarrassing, I'm extremely shy

After removal, does it always look much bigger??? How often do I need to remove it again???

If the hair is very long and curly, should I trim it with scissors first? Or will they trim it during the hair-removal session???
