Ok so the other morning, I performed oral sex on a guy that Im currently seeing. I've known him for about 5 months now. He told me that Im the only person he has had sexual contact with in the past 3 months. I went to the clinic two weeks ago and I seem to be fine because the clinic has not contacted me and told me anything.Anyways It was my first time doing it so I didnt do it very long because I personally didnt like it. I dont remember any semen coming out so I dont think I could have gotten anything from that. I know I keep feeling like I had to spit while performing oral sex and after because I just think I didnt like the idea of something in my mouth. In the middle of the night I started to experience a sort of burning in my throat which I know to most likely be a sore throat. All I Know is that my mom & sister had been sick with a cold/flu for the past few weeks but they didnt have any symptoms of a sore throat but the next morning my little brother and I both had a sore throat. My brother's kind of went away but mines is really bothering me...I took some medicine like Nyqill & Dayqill but it only has worked a little bit. I just want to know if you can get symptoms of an STI in the same day that you perform oral sex? Do you think its just a sore throat that I could have caught from m family or could I possibly have an STI? I dont know how to tell my mom if I do because she just recently took me to the clinic and she doesnt know that I just performed oral sex the other day....and we dont have medical insurance so im kinda confused on what to do because I dont want to be paranoid, have my mom run me to the doctor and have nothing wrong with me so im kinda confused on what to do...Can I get little help please???
