Contraception: Risks and Myths in Oral and Protected Sex - Obstetrics and Gynecology

When it comes to understanding the risks associated with oral sex, protected sex, and the potential for pregnancy, it's essential to clarify some misconceptions and provide accurate information based on medical knowledge.

1. Pregnancy Risk from Oral Sex and Kissing: Engaging in oral sex followed by kissing does not pose a risk for pregnancy. Pregnancy occurs when sperm fertilizes an egg, which typically happens through vaginal intercourse. In your scenario, even if there are secretions from the penis during oral sex, they do not lead to pregnancy unless they come into contact with the vaginal area. Therefore, the likelihood of pregnancy from the activities you described is virtually nonexistent.

2. Contraceptive Effectiveness with Condom Use: Using condoms consistently and correctly is one of the most effective methods of contraception. If you used a condom throughout the sexual encounter, even if you changed condoms due to dryness, the risk of pregnancy remains low, especially if ejaculation did not occur inside the vagina. It's crucial to ensure that the new condom is applied correctly and that there is no breakage during use. The effectiveness of condoms can be compromised if they are not used properly, but as long as you followed the guidelines, the risk of pregnancy is minimal.

3. Understanding Mucosal Contact and Pregnancy: The notion that contact with mucous membranes can lead to pregnancy is a misunderstanding. While sperm can survive in certain environments, it requires a direct pathway to the egg, which typically occurs through vaginal intercourse. If a condom is used properly, it should prevent any sperm from coming into contact with the vaginal mucosa, thus eliminating the risk of pregnancy.

4. Oral Health After Oral Sex: Experiencing a transparent, slightly white mucous in your mouth after oral sex and brushing your teeth can be normal. This could be a result of various factors, including the natural response of your oral mucosa to stimulation or the presence of saliva. However, if you notice persistent changes or discomfort, it would be wise to consult a healthcare professional for a thorough evaluation.

5. Menstrual Cycle and Pregnancy Risk: Regarding your menstrual cycle, if your period started on May 11 and you had protected sex on May 20 and 21, you were likely outside your fertile window. The typical ovulation period occurs around 14 days before the start of your next period, which means the risk of pregnancy during this time is generally lower. However, it's important to remember that individual cycles can vary, and factors such as stress or hormonal changes can affect ovulation.

In summary, while engaging in oral sex and using condoms significantly reduces the risk of sexually transmitted infections (STIs) and unintended pregnancies, it is essential to understand the proper use of contraceptives and the nature of sexual activities. Always communicate openly with your partner about sexual health and consider regular STI screenings if you are sexually active with multiple partners. If you have further concerns about your sexual health or contraceptive methods, consulting a healthcare provider is always a good step.
