What to eat to avoid turning it into paste? before massage session

[Kekkaishi]

When I go to a nude tantric massage, I always clean myself and my hole just in case the masseur decides to massage my hole.

I use enema to clean it, deep water, and it takes me well into an hour until I finish.
But even then, after a while I can feel the need to poop again due to pressure.

I always make an appointment late evening

What can I eat in the same day to avoid accumulating as much poop as possible?

thanks

@Kekkaishi Very simple...the day of your massage, stick to a liquid diet. No solid food. Especially with a late evening appointment.
