July 27th I had my first same sex experience with this guy. He performed oral anal on me which no dental dam was used or anything, and we actually went all the way and that was PROTECTED. 1 week and 5 days after this I started to experience symptoms like

Sore throat which could have Been from sleeping under air conditioner one night.
Headaches
Lymph nodes in my neck, groin, underarms, and inner thigh were bothering me
Fatigue
Nausea
And just a general feeling of not being well
Itching from I don't know what, but I'm really scared that I could have caught something from this guy even though he said he's 100% sure he's clean but I don't know what to believe. I'm better now I get headaches that come and go and one minute my lymph nodes aren't bothering me and the next it is.

Does anyone what's going on with me? Will I be okay? I'm I just stressing too much?

Go to get tested for STD's. That's the only way to know for sure, in the short term anyway.

If you kissed him after oral anal then you may have picked up some sort of digestive disease. Anything is possible lurking in the human feces and he just opened up a can of worms into your systme.

Just because your initial symptoms went away please go get checked out anyway as the lymph glands thing is NOT normal.

It is very possible from STD, to other illness that may come from contact.

Time for a complete physcial exam
