I can just repeat what has already been said - be respectful and friendly, try to make her feel comfortable with you, respect boundaries, ask before you do things (don't just shove a finger in her pussy), do not haggle over price, let her be in charge, give real compliments (say what you like about her, not what you think she wants to hear), relax and have fun. You may be a client paying for a service, but you are both still human beings, doing something that is very personal. And lastly, chemistry is a real thing. To find someone you have chemistry with see many different SWs and eventually you will meet ones that you naturally work well with (your favorite might not be that impressive to other guys, but with you she is amazing). Some start out great, and some start good and just keep getting better. Beyond that read reviews on Massage Planet, and DM members for more detailed information. Many SWs read what is written about them on MP so be discrete - they will eventually figure out who you are here. I have the experience of posting about what I like on MP (like kisses and hot breath on my neck) and then SWs have done that for me unprompted.
