3 weeks ago, I guy I had been seeing took a drink of alcohol from a glass of a girl who had recently gotten over an outbreak--she told him this some time later. He said she had no visible sores on her mouth whatsoever. 2 weeks ago, he and I pecked on the lips like 3 times. He went to the doctor, they told him it was highly unlikely that he would have it. He went for a follow up they said they could run a special blood test , but they said he would have gotten symptoms by now. What are the odds that I am infected?
