Every time I have sex it starts to hurt. Like I have a sore down below I have checked and I believe I don't. It gets worst when I have sex sing condom. And after sex its sore when I go to the toilet and itchy, and now its become swollen after sex. And still sore when going to the toilet and itchy. I don't know what to do. Am I mabe allergic to latex. I know when I where clothes to house cleaning , my hands become sore and itchy. Or would you say I have a STD .
