well even if your bf is a board certified medical doctor, you can't tell if someone has oral herpes just by looking at them!
if your bf has symptoms, he needs to be seen and get a proper exam and testing done.
if you haven't both had full std screenings done, it's a good idea to do so since you've been apart. I'm a trust no one type of gal and you want to know now what you each have, not months from now when you have active symptoms of a std. Odds are that neither of you have ever been tested for herpes either so while it's on your mind, asking for type specific herpes igg blood testing is the best course of action.

The symptoms are not of herpes or anything really, so i dont know
march his butt to the clinic !!
Please listen to Grace. There is something going on and it's best you both get to the bottom of it.
