Preparing to see a TS lady

Hi all,
I'm looking for some advice. Please excuse me if my question seems crude or stupid. What I am wondering is, while I have seen one ts already my my role was strictly active. If i was to try passive intercourse is there a need to prepare and if so how exactly do i go about it.
Apologies again if this seems stupid

Micralax or any lax-ant and a good bath before go( also if u not drive have a beer or 2)
Xxx

Make sure wallet filled it's the most important piece of advice u need first
