I hate long pubic hair. On me or her. I can live with very trim but hate bush, and if it is a turn off for me to find a pube stuck in my throat it must be the same for her as well
Pre-punt ritual. Shave - Face, balls ass crack. Low setting on hair trimmer over pubic area and ass cheeks as well.
I like rimming and strap on so next is a douche. If I know I'm clean I can relax knowing I will get good service down there
A long shower before leaving home. Nails trimmed, check for no unsightly nose hair, stray eyebrows, ear hair.
Clean teeth mouthwash
Avoid any cigs, booze, food until after punt.
Take my own deodorant, and mouthwash with me, in case it isn't available .
Still take a shower at hers, just a quick one but come out super clean and fresh. More mouthwash before leaving the bathroom
All of the above have never let me down for whenever I have had punted for a GFE / PSE
Some will tell you that it doesn't matter and that the WG will give you the same service however you turn up but I disagree and genuinely believe that you will receive much better attention if you make the effort for her as well
