I'm 19 years old and have never done anything sexual until 4 weeks ago where I recieved unprotected oral sex from someone with a history of having sexual partners. I have been very stressed and upset with myself that I put myself at risk for STDs. I got tested a week ago and it came back negative for HIV, Syphilis, Chlamydia, and Gonrrhrea. What I experienced a few days after our oral sex was pain in the tip and shaft of my penis. We did a lot of grinding/dry humping so I assumed that the pain was from that, and so did the nurse I talked to. The pain went away after a few days, but just this week I have been experiencing pain at the base of my penis, and every once in awhile in the tip, and testicles (mainly left, but a couple times right testicle).
I have not told my parents about this and have made multiple trips to Google to look for answers and nothing has helped me. I have made trips to our local health department as well just to ask about symptoms bc I am so stressed over them. I think about what happened 4 weeks ago almost constantly, and it's causing me to not enjoy everyday life and I worry all the time about what could be wrong with me. My family is also preparing to move so leaving my hometown where I grew up, which has me stressed as well bc its going to be a big change, especially bc I'm leaving for university next fall too.
Just giving you some background. But could my penis discomfort be related to me stressing over what could be wrong with my penis? I always think about how I wish I wouldn't have hungout with that girl. I have masturbated once since the hookup and it did not hurt to ejaculate either, although it was harder to. I used to masturbating twice a week but the desire to is not there anymore. I just want to enjoy life like I used to, without worry.
I also have been having digestion issues off and on during this time. A lot of gas and noises in my stomach, sometimes very loud along with loose bowel movements. Idk if that's related to anything but it has been bothersome as well
Could the dull pain be from my stress? Or is it from something underlying condition?
Update: The dull pain has gone away, I haven't noticed it for about 2-3 weeks. I still do feel stress and anxiety about my health due to the decision I made to have oral sex and moving. I think it could be stress related, or a mild form of prostatis. I havent been to the doctor. I noticed a white pimple on my scrotum, it does not hurt or itch and it is by itself. It has been there for about a week tho.. I think it might be my sebaceous glands acting up as they appear all over my scrotum, which is normal. It might just be a pimple, or an infected hair follicle. I always get worried about any itch around my privates as well, even tho Ive had no bumps show up besides the pimple. Ive masterbated a few times and noticed parts of my sperm are gel like, which i looked up and could be related to stress or prostatis. Other than that my semen looks normal. Any responses back would be great. I think it's stress related but I would like other people's opinions.
