About 3 weeks ago, I received a blowjob from a Turkish CSW in Asia. The CSW refused to kiss / lick any genital area that was not covered by the condom. She licked my nipples quite a bit, and I did the the same to her. She also was naked and her vagina was in contact with my thigh. I did finger her and then used the same hands to take off the condom after I ejaculated with the blowjob.
Since then I have had no typical symptoms but did have a slight stiff neck and slight headache for a couple of days in between. I was stupid enough to have oral sex with my fiance 3 days after this incident (I received unprotected fellatio) and full on sex with her 10 days after the encounter with the CSW.
without going into details, it is not possible for me to get tested and I am terrified of having contracted syphillis, chlaymidia or herpes, and more importantly having passed this on to my fiance. Someone please help - what are m chances of having caught an STI? If I come clean to my fiance my marriage will be off.
