Thing is not to plan the punt as if it is your first or last, the principles of punting remain the same. Do not do anything that will compromise your anonymity, your safety or financial position.
So even if you don't want to get a punting phone, get a sim card.
Don't punt on your doorstep.
Until you know what you are dealing with use a provider or establishment that has decent feedback or reviews.
Only take with you what you will need.
If you are unsure whether you want to go through with it or not then don't.
Be respectful and if you aren't going to go through with it then cancel.
Be honest, in terms of what you are after or your experience level, you don't get extra points for swaggering in like you know it all. You are actually paying so that you don't have to impress.
Be clean, it dont matter whether you are straight or gay or whatever - no one wants to suck a stinky cock or snog someone who breath smells like there is a fetid hamster rotting in their esophagus.
Afterwards write a review.
Don't fall in love with her no matter how good she is, it isn't real.
