Recently I was in Thailand and had sex with some sex workers there. I am pretty sure that all intercourse was condom protected (not 100% sure as one may have come of once as I was also drinking). About 5 days after returning which was also 13 days after my first sexual encounter (12 days after the one i am worried about) I noticed that I had an odd burning and sensitive sensation on my tongue and towards the back of the throat and up into the sinus a little bit. It is not painful just a bit tender and raw. I also have some reddish patches towards the back of my tongue. This symptom has persisted to varying degrees for about 2 weeks and is still present. I am slightly concerned that this might be primary HIV infection symptoms, to this date no other symptoms of note however (I am at approximately 4 weeks first contact, 3 weeks last contact)
The other thing that concerns me is that I was tested positive for Chlamydia. Since I am pretty sure I had no penis/ vaginal contact I am concerned that maybe I did. Is there is possible to get Chlamydia from receiving oral sex? Also If I did get some vaginal contact, how easy is it to contract Chlamydia compared to HIV?
Thanks and sorry for the long post.
