Some hospitals may not offer this service, but you can find such hospitals online by searching for facilities that provide post-exposure prophylaxis for HIV.

When it comes to understanding the risks of sexually transmitted diseases (STDs), including HIV, after engaging in sexual activities, it is crucial to evaluate the specific circumstances of the encounter. Based on your description of the activities you participated in—protected oral sex, protected vaginal intercourse, and unprotected manual stimulation—let's break down your concerns.

1. Risk Assessment:
- Protected Oral and Vaginal Sex: Using condoms significantly reduces the risk of transmitting STDs, including HIV. If the condoms were used correctly and did not break, the risk of transmission from these activities is low.
- Unprotected Manual Stimulation: This poses a higher risk, especially if there were any bodily fluids involved. If the sex worker had any cuts or sores on her hands or if there were any visible bodily fluids, the risk could increase. However, if your hands were intact and there was no direct contact with vaginal fluids, the risk remains relatively low.

2. Post-Exposure Prophylaxis (PEP):
- PEP is a treatment that can prevent HIV infection after potential exposure. It must be started within 72 hours of exposure and is most effective the sooner it is taken. Since you mentioned that you had unprotected manual stimulation, it is advisable to consult a healthcare provider immediately to discuss whether PEP is appropriate for you. They will assess your risk based on the details of your encounter and your health history.

3. Testing for STDs:
- It is recommended to get tested for STDs after any potential exposure. The window period for accurate testing varies by disease. For HIV, it is generally recommended to wait about 3 months for a conclusive result. However, some tests can detect HIV sooner (like the 4th generation tests).
- In addition to HIV testing, it is wise to test for other STDs, including chlamydia, gonorrhea, syphilis, and hepatitis B and C. Your healthcare provider can guide you on which tests are appropriate based on your sexual history and any symptoms you may be experiencing.

4. Symptoms and Follow-Up:
- If you are experiencing symptoms such as fatigue, loss of appetite, or sore throat, it is essential to consult a healthcare provider. While these symptoms can be associated with various conditions, they can also indicate an STD. Early diagnosis and treatment are crucial for managing any potential infections.

5. Anonymous Testing Options:
- If privacy is a concern, many clinics offer anonymous testing for STDs, including HIV. This can provide peace of mind and ensure that you receive the necessary care without fear of stigma.

In summary, while your risk of contracting an STD from the described activities is relatively low due to the use of condoms, the unprotected manual stimulation does warrant further evaluation. It is essential to consult a healthcare provider for personalized advice, consider PEP if applicable, and get tested for STDs to ensure your health and peace of mind. Remember, open communication with healthcare professionals is key to managing sexual health effectively.
