When assessing the risks associated with unprotected intercourse, it’s essential to understand the various factors that contribute to the likelihood of sexually transmitted infections (STIs), including HIV. In your case, you mentioned that during one instance of intercourse, you used a condom, while in the second instance, you did not. Although you did not ejaculate inside your partner, there are still important considerations to keep in mind.

Firstly, it is crucial to recognize that the use of condoms significantly reduces the risk of transmitting HIV and other STIs. Condoms act as a barrier that prevents the exchange of bodily fluids, which is the primary mode of transmission for these infections. However, during the second instance of intercourse without a condom, there is a potential risk, even if ejaculation did not occur inside the vagina. Pre-ejaculate fluid, which can be released before ejaculation, may contain HIV and other pathogens. Therefore, any unprotected sexual contact carries some level of risk.

In terms of the timing of your sexual encounters, the close interval between the two acts (about half an hour to an hour) does not inherently increase the risk of transmission, but it does mean that if there were any pathogens present, they could potentially be transmitted during that time. The fact that you wiped yourself with a tissue before the second act may have reduced some risk, but it is not a foolproof method for preventing transmission.

Regarding the need for post-exposure prophylaxis (PEP), this is a treatment that can be administered after potential exposure to HIV to reduce the likelihood of infection. PEP is most effective when taken within 72 hours of exposure and involves a course of antiretroviral medications for 28 days. Given that you had unprotected intercourse, it would be advisable to consult a healthcare provider as soon as possible to discuss your specific situation and determine whether PEP is appropriate for you.

In addition to considering PEP, it is also essential to get tested for STIs, including HIV, especially if you have had unprotected sex. Regular testing is a critical component of sexual health, and it is recommended that sexually active individuals get tested at least once a year or more frequently if they have multiple partners or engage in high-risk behaviors.

Lastly, it is important to have open and honest communication with your partner about sexual health and STI testing. Both partners should be aware of their STI status and take necessary precautions to protect each other. Practicing safe sex consistently, including the use of condoms, is the best way to reduce the risk of STIs.

In summary, while the use of a condom during one instance of intercourse provides a level of protection, the unprotected encounter does pose a risk, albeit potentially lower if no ejaculation occurred. Consulting a healthcare professional about PEP and getting tested for STIs is highly recommended to ensure your health and well-being.
