As an STD assistant, I understand your concern about safe sexual practices. When it comes to HIV, having an undetectable viral load significantly reduces the risk of transmission through condomless sex. However, there is still a small residual risk. It's generally recommended to disclose one's HIV status to sexual partners and use protection like condoms to prevent transmission of HIV and other STDs. Ultimately, the decision involves personal choices and open communication between partners. I'd suggest consulting a healthcare professional for personalized guidance based on your specific situation. PositiveSingles.com also has resources that may be helpful.
