The following are tips for a great session: my apologies if I am repeating the obvious.
Treat them like human beings:
So true that these ladies are people with real feelings. Treating the ladies as less than human because of their current profession should be avoided. It really reflects badly on the monger if they call them "hos" or I like to "fuck them." So I try to speak with them or make them smile. Laughter also goes a long way to build a connection. Yes, there are language barriers but making a connection is also fun. I've been told that some of these mongers don't even smile or even try to communicate, which leads to a less than stellar session.
Proper hygiene:
I also maintain good hygiene and I am well groomed. I take a shower before each session and yet, I still compy with a shower request. I've heard countless stories of mongers with terrible hygiene: greasy hair; body odor; facial stubble, and long finger nails (some mongers for whatever reason have one or more long finger nails). Korea females or Koreans in general are known for their hygiene (yes, there are exceptions). In addition, I keep an emergency monger kit in my car with baby wipes, nail clippers, nail files, mints, etc. in case I need to "freshen up" before a session.
Courtesy:
Go with the flow of the session and never force anything on the ladies. Some mongers go for a free for all and "pound the mound." Ask of she is ok during the session. I've heard stories of mongers having full on sex with no rest in between or courtesy for the provider. For example, a monger booked a 2 hour session and went on an all out pounding session that injured the provider's back. Of course the monger was banned.
Hope this helps. Have fun but always be respectful of the ladies.
