So i've been with a guy for a long time. we havent used condoms with eachother and the last time he got tested was dec. 20th. I have had unprotected sex two years ago and dont know if i might have an std. I have had pain in the tip of my penis for the last month or so off and on. I had a rash sort of thing on my inner thighs for two weeks at the begining of january. I'm wondering what i might have. I read that you have stomach pain with stds usually and started getting minute pain. i think it might be in my head but i really would like to know forsure. thank you
