Don't do raw.

Think with your big head, not your small head.

Don' bring so much money with you, just enough and maybe some spare when you go chiong. That way, cannot overspend.

Get tested frequently if you can.

Be prepared to say no or stop the action if she do something you don't want (like going raw).

Have enough rest. Yes, it's called chiong, but if you always tired, easier to fall sick.

Drink plenty of water.

Practice good hygiene and cleanliness.
