Hi, eight days ago I saw a sex worker where she gave me a hand job for 30 seconds and then put a condom on the head of my Penis with her hand's. She then put her mouth on the head to hold the condom in place and rolled the rest down. The oral sex lasted perhaps 60 seconds before I changed my mind and left. Three days later I noticed the tip of my urethra is slightly wet most of the time. Not sure if it's always been like this or I'm being paranoid. I'm also having pains in my lower stomach/pubic region. Can someone please help to tell me what are the chances I could of caught something? And what particular stds. I don't specifically remember her touching anywhere else but the condom with her mouth. Please help am very worried!
