I haven't had sex with the possible infected person in 4/5months. He used protection and it lasted for seconds because I pushed him off of me, neither of us ejaculated. Recently however, I have experienced a warm sensation when urinating. It's not painful, just warm. And it can feel quite sensitive, sometimes it stings a bit, when my boyfriend touches my vagina. I'm quite scared, could this be chlamydia? It's lasted a while now...
