Recently I explained to two providers that it is very unlikely that I am infected with herpes.
One of them did not want to meet at all, the other would not kiss on the lips.
( I was disappointed, since I wanted to meet a provider soon)

The reason I am unlikely to be infected is that I have very few partners.
 I meet providers 1-2 times a year , and have no other partners besides my monogamous long term.  

My long term partner has oral herpes.  However, she has never given me fellatio, and has not kissed me on the lips
since the first year we were together.   I have tested negative several times since we stopped mouth kissing.
I have never had a lesion or symptoms of infection.  

I think my biggest risk of being infected is from the providers I see, since they have many partners.
(herpes is quite common in the general population)

I wonder if many providers restrict behavior because the client's partner is infected?

I also suspect that most clients would not tell the providers, even if they were themselves
infected.
