I often have unprotected sex with my boyfriend. We stopped for about a month, and recently had sex again. (He's clean and I'm clean and he came inside me) This time after sex when I went to pee it burned severely and I had a hard time walking and sitting. The morning after my vagina was still sore and it itches if I scratch it, but otherwise its just a dull and out of the ordinary soreness. Am I allergic to his semen? Do I have a yeast infection? He hasn't complained of any itching or anything. Did he tear something?
