January 3rd, 2017 I had sex with a prostitute in dubai, unprotected oral sex and protected vaginal sex. No symptoms were appeared. Fast forward to February 7th, I had unprotected oral sex with another prostitute and I also went down on her for 10 seconds at the most, licked down there 3-4 times. But the vaginal sex was protected. I had gotten a sore throat and a slight cold a week after the last interaction. 3 weeks after the last interaction I got tested for ghonorea and chlymydia and they both came back negative. I got a culture test for strep throat which also came back negative. About a week ago my anus started to irritate and it would hurt after a bowl movement and I have had diarrhea twice or 3 times in the past week or so. My foreskin hurts every time I pull on it (i masturbate once a day maybe twice). I have a sore throat, a blister in my mouth which lasted for 3 days and is going away, and dry mouth/nose, my tonsils are swollen and I do get a throwing up feeling from time to time when i burp or swallow sometimes. I'm getting eczema where I usually get it(on my hands/knuckles) and I do get tingling feelings in my legs and arms. I have had a throat infection back in September 2016 and I do have asthma. That's everything I know and I'm worried I may have an STD, if anybody could help me it would be great, thank you.
