Assessing Risks: Pre and Post-Sexual Activity Hygiene Practices - Urology

Is washing once before sexual intercourse and once after sexual intercourse a low-risk practice?


Hello Dr.
Du, I have a few questions I would like to ask you:
1.
I had sexual intercourse with my girlfriend on February 21.
During this, she performed oral sex on me without a condom, but she rinsed her mouth with hot water beforehand.
Does this lower the risk?
2.
I have shaved my pubic hair; will this have any impact on sexual activity?
3.
My girlfriend and I took a shower before engaging in sexual activity, and we cleaned ourselves again afterward.
Does this lower the risk?
4.
How long after sexual intercourse should I wait to get tested? If I am concerned and want to go to the hospital for testing, how should I communicate this at the front desk?
5.
Is it sufficient to see a urologist for testing, or should I undergo a full physical examination?

Hello: Your questions all have a premise, which is that one of the two individuals has a sexually transmitted infection (STI).
Additionally, it is important to pay attention to safe sexual practices.
You can refer to http://www.isu.edu.tw/upload/04/7/news/postfile_60883.pdf 1) If safe sexual practices are not followed, there is still a risk.
2) No.
3) Cleaning can help somewhat, but safe sexual practices are still necessary.
4) Personally, I recommend testing at 6 weeks and again at 3 months; you should consult a urologist.
5) The urology department can handle this.

When assessing the risks associated with sexual activity, especially in the context of potential sexually transmitted infections (STIs) such as HIV, it is essential to consider various factors, including the nature of the sexual acts, hygiene practices, and the timing of testing for STIs. Here’s a comprehensive response to your questions based on medical knowledge and guidelines.

1. Oral Sex and Hygiene Practices: Your girlfriend rinsing her mouth with hot water before performing oral sex may reduce the risk of transmitting some infections, but it does not eliminate the risk entirely. The act of oral sex itself can still pose a risk for STIs, including HIV, especially if there are cuts or sores in the mouth or on the genitals. While rinsing may help reduce the bacterial load, it is not a foolproof method for preventing infections. The risk is generally lower compared to unprotected vaginal or anal intercourse, but it is still present.

2. Shaving Pubic Hair: Shaving or trimming pubic hair does not inherently increase or decrease the risk of STIs. However, if shaving causes micro-abrasions or cuts, it could potentially increase the risk of infection if there is contact with infected bodily fluids. It is crucial to ensure that any grooming is done carefully to minimize the risk of skin irritation or injury.

3. Hygiene Before and After Sexual Activity: Engaging in sexual activity after both partners have showered can help reduce the risk of infections by removing bacteria and other pathogens from the skin. Additionally, cleaning up after sex is a good practice, as it can help prevent the spread of bacteria and reduce the risk of urinary tract infections (UTIs). While these practices lower the risk of infections, they do not eliminate it entirely, especially regarding STIs.

4. Timing for STI Testing: It is generally recommended to wait at least 2-4 weeks after potential exposure to get tested for STIs, including HIV. However, for HIV, the window period can be up to 3 months for conclusive results. If you are feeling anxious about your sexual health, it is advisable to get tested sooner, but be aware that results may not be definitive until the window period has passed. When visiting a healthcare facility, you can simply inform the receptionist that you would like to get tested for STIs, and they will guide you through the process.

5. Type of Testing Required: For STI testing, it is typically sufficient to see a urologist or a general practitioner who can perform the necessary tests. They may conduct a urine test, blood test, or swab test depending on the specific STIs you are concerned about. A full health check-up may not be necessary unless you have other health concerns or symptoms that need to be addressed.

In summary, while certain hygiene practices can reduce the risk of STIs, they do not completely eliminate it. It is essential to communicate openly with sexual partners about risks and testing, and to engage in safe sex practices, such as using condoms consistently and correctly. Regular testing is a proactive way to manage sexual health, especially if you have concerns about potential exposure to STIs. If you have any symptoms or concerns, seeking medical advice promptly is always a good idea.
