I think your question might be best placed on the "providers only" board first.  If you don't get a satisfying answer there (though I suspect you would) you might try the "Legal Corner" board.  Though I'm a client, not a provider my advice would be ... if you are uncomfortable, trust your instincts and bail.

Many providers state on their websites that emails of that nature will simply be deleted.  It's not a bad policy.  Legalities aside (although some liability is probably there), you're likely setting yourself up with someone who's unfamiliar with the rules of the game.  Why do that to yourself?

IMHO a man who doesn't know how to act via e-mail, probably won't in the room either.

Granted we are all pigs, but that's no reason for bad manners.  LOL

Starting new as you are, follow the earlier advice -- stay with gentlemen.  There are enough of us out there.  Yes, we're all horny toads, but first impressions matter and the nimrods out there that we compete with for your affection need to learn to treat you with class, not 8th grade behavior. Aim high, and don't settle for less.  We "good" guys treat quality women well....

but would never say so in an e-mail.  Many providers for good reason, simply delete those notes and ignore the senders - now it is a totally different thing once the session has started, to voice one's preferences.
Bottom line - stay away from those unless it is time to play.
Seek further advice from your fellow providers - being a newbie for the ladies is no different that being one for the clients - you will be surprised I think by the support you have in the community if you just ask.

My suggestion is to delete emails of this nature, and i agree with another poster who said that if the guy is like that in emails he may very well be rude or worse in the room, and we do not want you to experience that.
Also a sweet lil gal form buffalo (ciarahasfun)just posted on the national board what she calls her PHD, it is a seaies of her blogs. That information may help you. There are many many wonderful sweet gals on TER who I am sure will help you , just ask them

Also if I may be so bold as to ask you to post your web site and what is you location heck you never know maybe one day we can have a cup of coffee together.

Thank You

Emme, where do you advertise?

Do you advertise on the NY or Philly TER board?  I've searched both for you and haven't found you.  I would love to see you next time I come to Jersey.  If you advertise on TER then you probably won't get creepy dumbasses asking explicit questions.  

To answer your question, DO NOT say you will let him lick you.  The best way is to have reviews they can look at.  If you don't have any yet, then try using code words or abbreviations when communicating to let them know what you are willing to do.  It's always a good idea to verify your client before speaking explicitly.

Emme, you would do yourself a huge favor if you got VIP access

to TER.  There is a lot of info that people will share with you privately.  And to use TER's private mail system you need VIP access.  Good people like Tori or Stacy (sinsoftheflesh) will offer you important advice that can't be posted here.

Then after you get 3 reviews you can request access to the providers only board and get even more info.

If you want to be safe, this is the best way to do it.  20 bucks might save your life.
