Infection Inquiry 2
Hello doctor, I am the patient from the previous case #129010.
Last time, I mentioned that I was sprayed with an unknown liquid by a pervert at the night market, and I am concerned it might be semen.
It got on my right buttock and right thigh.
As soon as I got home, I washed with warm water and discarded my underwear and shorts, and I repeatedly scrubbed the affected areas.
You mentioned that there is no possibility of infection or pregnancy, so I don't need to worry now, right? If it was semen, sperm wouldn't swim from the buttocks to the vagina on its own, would it? At that time, I was nervous and sweating, and the vagina is weakly acidic while sperm is weakly alkaline, so sperm needs the protection of semen; otherwise, they would die as soon as they enter the vagina.
I apologize for being easily anxious since childhood.
I have never engaged in any sexual activity from childhood to now, but I do occasionally masturbate.
Thank you, doctor.

More Info
It sounds like you have been through a very stressful and concerning situation, and it's completely understandable to have worries about potential infections after an unwanted exposure. Let's address your concerns from a gynecological and medical perspective.
Firstly, regarding the incident where you were sprayed with an unknown liquid, it's important to clarify a few points about HIV transmission and the nature of sperm. HIV (Human Immunodeficiency Virus) is primarily transmitted through specific bodily fluids, including blood, semen, vaginal fluids, and breast milk. For transmission to occur, the virus must enter the bloodstream, which typically happens through mucous membranes found in the genital area, rectum, or open wounds.
In your case, if the liquid you were sprayed with was indeed semen, the risk of HIV transmission is extremely low if it did not come into direct contact with your mucous membranes. The vagina and anus are the primary entry points for the virus, and sperm cannot swim from the skin of your thigh or buttocks to your vagina. Additionally, sperm exposed to air or non-ideal conditions (like being on the skin) typically die quickly, especially without the protective environment of seminal fluid.
You mentioned washing the affected areas immediately with warm water, which is a good practice. Washing the skin can help remove any potential pathogens, and since you did not have any direct contact with the semen entering your vagina, the risk of HIV infection is negligible.
Regarding your concerns about pregnancy, it is also important to note that pregnancy can only occur when sperm is deposited in the vagina or near the vaginal opening, allowing it to travel through the cervix into the uterus. Since you did not engage in any sexual activity that would allow for this, the risk of pregnancy is also non-existent.
Your understanding of the acidic environment of the vagina is correct; it is indeed acidic, which is not conducive to sperm survival outside of seminal fluid. This further reduces the likelihood of any sperm surviving long enough to cause pregnancy or infection.
It’s also worth noting that anxiety and stress can exacerbate feelings of worry, especially regarding health concerns. If you find yourself feeling overwhelmed, it may be beneficial to speak with a healthcare professional or a counselor who can provide support and help you manage your anxiety.
In summary, based on the information provided, it is highly unlikely that you are at risk for HIV or pregnancy from the incident you described. However, if you continue to have concerns or experience any unusual symptoms, it would be wise to consult with a healthcare provider for further evaluation and peace of mind. Regular check-ups and open communication with your healthcare provider can help alleviate fears and ensure your overall health and well-being.
