When it comes to understanding the risks of sexually transmitted diseases (STDs) associated with oral sex and other sexual activities, it's crucial to consider the nature of the activities involved, the presence of any infections in either partner, and the protective measures taken during these encounters.

In your brother's case, he engaged in oral sex with a sex worker, which is a common sexual practice. While oral sex is generally considered to be lower risk compared to vaginal or anal intercourse, it is not without its risks. STDs such as HIV, syphilis, gonorrhea, and herpes can still be transmitted through oral sex, especially if there are cuts or sores in the mouth or throat, or if the partner has an active infection.

1. Oral Sex: The act of oral sex itself can transmit infections. If the sex worker had any STDs, there is a risk of transmission to your brother, particularly if there were any abrasions or open sores in the mouth. The risk of HIV transmission through oral sex is significantly lower than through anal or vaginal sex, but it is not zero. Gonorrhea and chlamydia can also be transmitted through oral sex, leading to throat infections.

2. Kissing and Nipple Sucking: Engaging in activities such as sucking on each other's nipples or kissing can also pose risks, especially if there are any cuts or sores in the mouth. While the risk of transmitting STDs through these activities is generally lower, it is still possible, particularly for infections like herpes.

3. Hand-to-Genital Contact: The act of touching the anus or genitals with hands can also pose a risk if there are infectious agents present on the skin or bodily fluids. If the sex worker had any infections, there is a potential risk of transmission through this contact.

4. Use of Condoms: The fact that your brother used a condom during oral sex significantly reduces the risk of transmission of STDs. Condoms are effective barriers against many infections, including HIV, gonorrhea, and chlamydia. However, they do not provide complete protection against all STDs, particularly those that can be transmitted through skin-to-skin contact, such as herpes and HPV.

In summary, while the risk of contracting STDs from the activities described is lower due to the use of condoms, it is not entirely eliminated. If your brother is concerned about potential exposure to STDs, it is advisable for him to get tested. Regular testing is an important part of sexual health, especially after engaging in sexual activities with new partners.
Moreover, it is essential to maintain open communication with sexual partners about sexual health and to practice safer sex methods consistently. If any symptoms arise, such as unusual discharge, sores, or pain, seeking medical advice promptly is crucial.
In conclusion, while the activities your brother engaged in carry some risk of STD transmission, the use of condoms and the nature of the activities can mitigate that risk. Regular testing and open communication about sexual health are key components of maintaining sexual health and preventing the spread of STDs.
