I just talked to him, He is not worried about the situation. I hope he's right.
Did you just give him herpes? Maybe.
If he already has oral hsv1 that will offer him significant protection against getting it genitally. 67% of people under 50 have hsv1 globally.
Did you talk about this before the encounter? Do you know if he has hsv1?
Greetings. Neither herpes nor syphilis sores form so quickly, it takes days for herpes and weeks for syphilis. You probably already have oral herpes, so I see no reason to freak out.
Freaking out is the worst thing you can do: it never helps but always puts a lot of pressure on your mind, producing even more symptoms.
