http://www.ashastd.org/herpes/herpes_learn_oralherpes.cfm is a terrific link for more reading on oral herpes.
definitely you need to talk to your guy about this since it's worrying you. why not suggest that you both go and get full std screenings and make sure that they include herpes igg blood tests and go from there?
but i never had sex just him ,so should i still get tested?
and we both are both under age im 16 and he is 15, so would we need a parent to go with us and sign for us.Is there a possibly that he does have herpes given what I said?
You are both over 14 and in almost all states, you have complete autonomy and don't need parental permission for much of anything medical.
He could have oral herpes. He could have a dermatitis of some sort going on. He could have a bacterial infection. He certainly needs a better work up to see what is causing his symptoms.
