Wearing someone else's unwashed pants does not pose a significant risk of contracting a sexually transmitted infection (STI). STIs are primarily transmitted through direct sexual contact, and the pathogens responsible for these infections typically do not survive long outside the human body. However, it is always advisable to practice good hygiene and avoid sharing personal clothing items to minimize any potential risk?
Hello, doctor.
A year ago, I accidentally wore someone else's pants without thinking about it (I was wearing my own underwear).
When I got home, I wore the pants while watching adult films and ejaculated on them.
Can I get a sexually transmitted infection (STI) from this? (I'm not sure if the owner had ejaculated on those pants.) Is the risk of contracting HIV from sharing utensils with others very high? If I often shared utensils in high school and I'm feeling uneasy about it, should I get tested?

Hello: You cannot contract sexually transmitted infections (STIs) through casual contact, but it is possible to develop skin conditions.
Sharing utensils does not transmit HIV, but it is not recommended to share utensils (which is why we advocate for the use of serving chopsticks).
If you notice any abnormal skin growths, redness, discharge, or blisters, you should seek medical attention.
Thank you for your inquiry.

More Info
When it comes to the transmission of sexually transmitted diseases (STDs) through clothing, particularly wearing someone else's unwashed pants, the risk is generally considered to be very low. STDs are primarily transmitted through direct sexual contact, which involves the exchange of bodily fluids such as semen, vaginal secretions, or blood. Here’s a breakdown of the concerns you raised:
1. Wearing Someone Else's Pants: If you wore someone else's pants without any direct skin-to-skin contact (for example, if you were wearing your own underwear), the likelihood of contracting an STD is minimal. While it is theoretically possible for bodily fluids to remain on the fabric, the transmission of STDs through clothing is not a common route of infection. Most pathogens that cause STDs do not survive long outside the human body, especially on fabric.
2. Semen on Clothing: If the previous owner of the pants had semen on them, the risk of transmission would still be low, especially if you were wearing your own underwear. The fluids would need to come into direct contact with mucous membranes (such as those found in the genital area) for transmission to occur. Additionally, the viability of pathogens in semen decreases significantly once exposed to air and fabric.
3. Sharing Utensils and HIV: Regarding the concern about sharing utensils and the risk of HIV transmission, it is important to note that HIV is not transmitted through casual contact or sharing food and utensils. The virus requires specific conditions to be transmitted, primarily through sexual contact, sharing needles, or from mother to child during childbirth or breastfeeding. Therefore, the risk of contracting HIV from sharing utensils is extremely low. If you are concerned about your risk of HIV or other STDs, it is advisable to get tested, especially if you have had unprotected sex or other risk factors.
4. General Hygiene Practices: While the risk of contracting STDs from clothing is low, it is always a good practice to maintain good hygiene. Washing clothes thoroughly with detergent and drying them properly can help eliminate any potential pathogens. If you are ever in doubt about the cleanliness of borrowed clothing, it’s best to wash them before wearing.
5. When to Seek Medical Advice: If you experience any unusual symptoms such as sores, rashes, or discharge, it is important to consult a healthcare provider. Regular check-ups and screenings for STDs are also recommended for sexually active individuals, especially if you have multiple partners or engage in unprotected sex.
In summary, while the concern about contracting STDs from wearing someone else's unwashed pants is understandable, the actual risk is very low, particularly if you were wearing your own underwear. Sharing utensils does not pose a significant risk for HIV transmission either. If you have ongoing concerns about your sexual health, consider discussing them with a healthcare professional who can provide personalized advice and testing options.
