Hello! Dear doctor in this forum. I’ll begin introducing myself and my situation as short and clear as possible. My name is Yusuke, a 22-year-old Japanese boy. 3 months ago I travelled to Colombia, the south American country and I hired a male tourist guide there. During the trip he was nice and friendly, and after the trip he asked me if I would like to try sex with him. I admit that I am bisexual and I’ve never tried a gay sex so I agreed. During the sex, I penetrated him with condom, which was only covering approximately 2/3 of my penis when I checked it after I ejaculated. This is my first worry. And the most worrying thing is that he’s put his penis on my anus, but I am sure that he didn’t penetrated it cause I hadn’t felt any pain or the least feeling like penetration. We did mutual blowjob to each other without condom. He is now working in Spain as massage worker and when I told him my worrying he told me that he held a card of health which is needed in Spain. However he also admitted that he had gained much money by doing this, which means he had a lot of gay sex before, but he insisted in that he had always used condom. I am still so scared and I regretted so much now. During these three months I haven’t got any symptoms, such as fever, flu-like symptoms or rush, etc. Will I have any risk? A million thanks to you!
