It is very contagous

I can't believe you even need to ask this.

Absolutely not. you need to cancel for health reasons. you should cancel if you are catching a cold.
she doesn't want your nasty itch. would you expect her to cancel if she had a yeast infection or worst? I know this is a very "me" oriented business but there is a point where you need to draw the line and consider how what you do affects others.

Re: Probably the first time asked...

and spraying a little tinactin or whatever wont clear it up in a couple days? wow.

and see if it clears up in a day or 2.

I have had mild cases go away overnight. (That might have just been chafing)

It's worth a try.

Seriously? Please cancel with her and explain WHY she will thank you for that!!!

Not sure what kind of itch I got, but it happened to me few months ago.
I have huge natural breasts and guys LOVE to do Russian with me.
I had three clients doing with me in one day --- then couple days later I had this itch on my left nipple aureola and I could not stop scratching.
It developed a patch of dry skin, and I was freaking out.
I stopped offering my breasts for sucking, touching and Russian right away and went to a dermatologist.
He prescribed a cortisone based cream and took about two weeks to get rid of it.
When you guys have ANY skin condition, please please please do not patronize ANY of us.
These guys I saw didn't have any visible rashes on their groins, but who knows, they could just have contact with something and did pass to me.
I am seriously considering not let guys do Russian or even suck on my breasts anymore, because I get freaked out thinking about getting rashes again.
It was annoying and I had to be out of work for two weeks until my Doctor told me I could resume my normal activities (he knows what I do, I had to tell him to get the proper treatment).

PLEASE do the proper thing and CANCEL you appointment with this lady! She will be grateful if you do and explain WHY!!!

How would you want to be treated? Would you want someone to risk giving you something or would you prefer they wait until they were safe and itchy free? If this stuff doesn't go away before the encounter, cancel it and reschedule.
