I understand your concern about the risks of contracting sexually transmitted infections (STIs) like HIV, HPV, or others when having multiple sexual partners. As an STD assistant, I want to provide you with accurate and supportive information on this topic.

Even if all partners appear "clean" or asymptomatic, there is still a risk of transmitting certain STIs through sexual contact. Many STIs, including HIV and HPV, can be present without visible symptoms, and the only way to know for sure is through proper testing.

The risk increases with the number of sexual partners, as well as the specific sexual activities engaged in. Using protection like condoms and dental dams can reduce but not eliminate the risk entirely.

It's important to have open and honest conversations with sexual partners about testing history, get regularly tested yourself, and practice safer sex methods consistently.

I would advise consulting a healthcare professional for personalized guidance based on your specific situation and sexual history. They can provide more detailed information, testing recommendations, and advice on reducing your risk.

Remember, there is no need to feel ashamed or stigmatized. Healthcare providers are there to support your sexual health in a non-judgmental manner. Taking proactive steps to protect yourself and your partners is a responsible approach.
