Safe Sex Practices: Your Questions Answered by a Urologist - Urology

Inquire about safe sexual practices and measures with your doctor?


Doctor, I would like to ask how conditions like genital warts or syphilis are contracted.
I have some doubts about safe sex practices; could you help clarify my understanding? I believe that safe sex requires the consistent use of condoms and dental dams.
However, if I want to have children in the future, wouldn't that mean I have to have unprotected sex? If both partners are healthy, does unprotected oral or other sexual intercourse still pose a risk for syphilis or other STIs? Additionally, even if both partners are healthy, is it less hygienic and could it lead to bacterial infections, such as urethritis or gynecological issues? So, is it correct to say that it's better to use condoms unless trying to conceive?
I also have another question: if I am healthy and use a condom for oral sex, but some semen or pre-ejaculate accidentally spills out, could that transmit syphilis or other STIs to my partner? If both partners are healthy, is it safe to have unprotected sex, or is it still better to use condoms?
Lastly, I've heard of people contracting genital warts in public restrooms.
Why does this happen? Is it due to the unsanitary conditions of the restroom, or could it be that someone with genital warts left the virus on the toilet? I apologize for the lengthy questions.

Understanding safe sex practices is crucial for preventing sexually transmitted infections (STIs) such as syphilis and HPV (commonly referred to as "cauliflower" due to the appearance of warts). Your concerns about safe sex and the potential risks involved are valid and deserve a thorough explanation.

Firstly, STIs are primarily transmitted through direct contact with infected bodily fluids, including vaginal secretions, semen, and blood. For example, syphilis is spread through direct contact with syphilis sores during sexual activity, while HPV can be transmitted through skin-to-skin contact, even when an infected person does not have visible warts.

Your understanding of safe sex practices is mostly correct. The consistent and correct use of condoms and dental dams during sexual activities significantly reduces the risk of transmitting STIs. Condoms are effective barriers that prevent the exchange of bodily fluids, which is essential in preventing infections. Dental dams serve a similar purpose for oral sex, providing a barrier between the mouth and the genital area.

Regarding your question about wanting to conceive a child, it is true that unprotected sex is necessary for conception. However, if both partners are healthy and have been tested for STIs, the risk of transmitting infections during unprotected sex is lower. It is advisable to have open and honest discussions with your partner about your sexual health and to get tested together before deciding to have unprotected sex.

You also raised a valid point about hygiene and the potential for bacterial infections, such as urinary tract infections (UTIs) or gynecological infections, when engaging in unprotected sex. Even if both partners are healthy, unprotected sex can introduce bacteria into the urinary tract or vaginal area, leading to infections. Therefore, maintaining good hygiene before and after sexual activity is essential, regardless of whether condoms are used.

As for your concern about the accidental exposure to semen or pre-ejaculate during oral sex, it is important to note that while the risk of transmitting STIs is lower compared to vaginal or anal intercourse, it is not zero. If an infected person’s bodily fluids come into contact with mucous membranes in the mouth, there is still a risk of transmission. Therefore, using protection during oral sex is recommended to minimize this risk.

Regarding your question about contracting HPV or other infections in public restrooms, it is important to clarify that STIs are not typically transmitted through surfaces like toilet seats. HPV and other STIs require direct skin-to-skin contact or contact with infected bodily fluids. However, public restrooms can harbor bacteria and other pathogens, which can lead to non-STI-related infections. Good hygiene practices, such as washing hands and avoiding direct contact with potentially contaminated surfaces, can help reduce the risk of infections.

In summary, while the desire to have unprotected sex for the purpose of conception is understandable, it is crucial to ensure that both partners are healthy and have been tested for STIs. Using condoms and dental dams during sexual activities is the best way to protect against STIs and maintain overall sexual health. If you have further concerns or specific situations that you would like to discuss, consulting with a healthcare provider or a urologist can provide personalized advice and guidance.
