Hi, i am a male and i had unprotected sex once for just 5 mins then i put on condom, my partner told me that she is hiv and std negative howver i dont know her that well. The day after we had sex, i had a cold and sore throat for about a week and a half. I asked her and she told me that might be because of the fact that she just recently got rid of a cold before we had sex. It has been 4 months till now, i havent experienced any fatigue, weight loss or burning during urination. However tho my penis head got more dry and wrinkled. Please let me know if i have std or no. Thanks
