Hi Doctors... This is kind of worrying me. As last week i met this escort then we had unprotected oral sex and french kissing (without any sexual intercourse). During the oral sex and kissing i actually have a small ucler on the tip of my tongue... that ucler is due to a burn previously. A week later which is now, my throat is kind of feeling heaty and in the morning my body feel cold. I did went for a jog in the early morning and have eat some spicy food recently, but i cannot confirm whether this because i was infected by STDs. Please advice me...
