When it comes to understanding the risks of pregnancy, particularly in the context of external ejaculation, it’s important to clarify a few key points about how pregnancy occurs and the factors that influence the likelihood of conception.

Firstly, pregnancy typically occurs when sperm fertilizes an egg. For this to happen, sperm must be deposited in or near the vaginal canal, allowing it to travel through the cervix and into the uterus where it can meet an egg. In your scenario, the sperm was initially deposited on the external area (the buttocks) and then wiped towards the vaginal area. While the likelihood of pregnancy from this method is significantly lower than direct ejaculation into the vagina, it is not entirely impossible.

Sperm can survive for a short period outside the body, but they are highly sensitive to environmental conditions. Factors such as temperature, exposure to air, and the surface they are on can all affect sperm viability. When sperm is wiped from the skin and then transferred to the vaginal area, there is a small chance that some viable sperm could make it into the vagina and potentially lead to pregnancy. However, this risk is generally considered low.

To quantify the risk, studies suggest that the chances of pregnancy from external ejaculation are significantly lower than from direct ejaculation into the vagina. The exact probability can vary based on several factors, including the timing of the menstrual cycle, the presence of viable sperm, and individual fertility factors. If you are in the fertile window of your cycle (the days leading up to and including ovulation), the risk of pregnancy increases, but it remains relatively low compared to direct ejaculation.

If you are concerned about the possibility of pregnancy, it is advisable to take a pregnancy test if your period is late or if you experience any early signs of pregnancy. Additionally, if you are not planning to conceive, it is crucial to consider effective contraception methods to prevent unintended pregnancies in the future. Options include hormonal contraceptives (like birth control pills), barrier methods (like condoms), intrauterine devices (IUDs), and other forms of birth control.

In conclusion, while the likelihood of becoming pregnant from external ejaculation is low, it is not zero. If you have further concerns or questions about your reproductive health, it would be beneficial to consult with a healthcare provider who can offer personalized advice and guidance based on your specific circumstances. They can also provide information on effective contraception methods to help you manage your reproductive health according to your plans and desires.
