When it comes to the transmission of sexually transmitted diseases (STDs) through activities such as oral sex and urine drinking, it is essential to understand the risks involved, especially considering the specific circumstances you mentioned, such as having dental issues and engaging in various sexual practices.


Oral Sex and STD Transmission
Oral sex can potentially transmit STDs, including HIV, herpes, gonorrhea, and syphilis, among others. The risk of transmission is influenced by several factors, including the presence of cuts or sores in the mouth, the viral load of the infected partner, and the type of sexual activity performed. In your case, having dental issues like cavities and periodontal disease could increase the risk of transmission. Open sores or bleeding gums can serve as entry points for pathogens, making oral sex a riskier activity if one partner is infected.

1. HIV Transmission: While the risk of contracting HIV through oral sex is lower than through vaginal or anal intercourse, it is not zero. If your girlfriend is HIV-positive, there is a potential risk, especially if there are any cuts or sores in your mouth.

2. Other STDs: Other STDs can be transmitted through oral sex as well. If your girlfriend has an active infection, the risk of transmission increases, particularly if there are any abrasions in your mouth.


Drinking Urine and STD Risks
Drinking urine is generally considered a low-risk activity for STD transmission. However, if urine contains pathogens (which can occur if the person has an active infection), there is a theoretical risk, albeit very low. The presence of any cuts or sores in your mouth could increase this risk slightly, but it is still considered minimal compared to other sexual activities.


Wearing Underwear and STD Risks
Wearing your girlfriend's underwear that has been in contact with her vaginal secretions or urine does carry some risk, albeit low. The primary concern would be if there are any pathogens present in those fluids. If you have any cuts or abrasions on your skin, especially around the genital area, there is a potential risk for transmission of infections like HPV (which can cause genital warts) or other STDs.


Conclusion and Recommendations
Given your situation, here are some recommendations:
1. Regular Testing: Both you and your girlfriend should get regularly tested for STDs, especially if you are engaging in high-risk behaviors. Knowing your status can help you make informed decisions about your sexual health.

2. Oral Health: Address your dental issues. Maintaining good oral hygiene and treating any dental problems can reduce the risk of transmission during oral sex.

3. Use Protection: Whenever possible, use barriers such as condoms or dental dams during oral sex to reduce the risk of STD transmission.

4. Communication: Openly discuss sexual health with your partner. Ensure that both of you are aware of each other's health status and any potential risks involved in your sexual practices.

In summary, while certain activities may carry a lower risk of STD transmission, the presence of dental issues, open sores, and the nature of your sexual practices can influence that risk. It is always best to prioritize safety and health through regular testing and protective measures.
