Understanding the risks of pregnancy after intercourse, especially in the context of pre-ejaculation and subsequent actions, is crucial for anyone who is sexually active. In your scenario, where there was an initial external ejaculation followed by oral contact and then vaginal intercourse after a brief interval, several factors come into play regarding the likelihood of pregnancy.

Firstly, it’s important to understand that pre-ejaculatory fluid, often referred to as "pre-cum," can contain sperm. While the concentration of sperm in pre-ejaculatory fluid is generally lower than in ejaculate, it is still possible for pregnancy to occur if sperm is present. If the initial ejaculation occurred outside the vagina, and there was no direct transfer of sperm into the vaginal canal, the risk of pregnancy is reduced but not eliminated.

When you mention licking and using a tissue before engaging in vaginal intercourse, these actions may further reduce the risk of sperm transfer. However, it is essential to note that if any sperm were to remain on the genital area or if there was any contact with pre-ejaculatory fluid, there is still a potential risk for pregnancy. The time interval of five minutes may not be sufficient to completely eliminate any viable sperm that could lead to fertilization.

In terms of statistical likelihood, studies suggest that the chances of pregnancy from pre-ejaculatory fluid are relatively low but not negligible. If no ejaculation occurred inside the vagina and there was no direct transfer of sperm, the probability of pregnancy could be estimated to be less than 10%. However, this is a rough estimate and can vary based on individual circumstances, including the timing of the menstrual cycle and the presence of viable sperm.

To further understand the risks, it is crucial to consider the timing of intercourse in relation to the menstrual cycle. If intercourse occurs during the fertile window (typically days 10 to 14 of a 28-day cycle), the likelihood of pregnancy increases significantly. Conversely, if intercourse occurs outside this window, the chances are lower.

For those who are concerned about unintended pregnancy, it is advisable to consider reliable contraceptive methods. Options include hormonal birth control, condoms, or emergency contraception if unprotected intercourse occurs. Emergency contraception, such as Plan B, can be effective if taken within 72 hours after unprotected intercourse, but it is most effective the sooner it is taken.

In conclusion, while the actions you described may reduce the risk of pregnancy, they do not eliminate it entirely. If you are concerned about the possibility of pregnancy, consider taking a home pregnancy test if your period is late or consult with a healthcare provider for further guidance. Additionally, discussing contraceptive options with a healthcare professional can help you make informed decisions about your sexual health and family planning.
