My boyfriend accidentally ejaculated on my calf while masturbating.
I wiped it off immediately, but about two hours later, when I got home, I rubbed the calf with my other foot.
I’m not sure if it’s psychological, but it felt strange to touch.
Basically, my leg was dry.
My boyfriend told me that dried semen would feel that way, so is there any residual semen left on my leg?
Answer: It’s normal to feel a strange sensation after your boyfriend accidentally ejaculated on your calf and the semen dried.
Later, I used a tissue dampened with water to wipe my calf, and after that, I touched my vulva when I went to the bathroom.
Could this lead to pregnancy? It seemed like it was during a fertile period.
Answer: Wiping your calf with a damp tissue and then touching your vulva afterward will not lead to pregnancy.

More Info

The concern about the possibility of pregnancy from contact with dried semen on the skin is a common question, particularly among individuals who are trying to understand the mechanics of conception and the viability of sperm outside the body. To address your question, it is important to clarify a few key points regarding sperm viability and the conditions necessary for pregnancy to occur.

Firstly, sperm must be in a viable state to fertilize an egg. When semen is ejaculated, it contains sperm that are capable of swimming and fertilizing an egg. However, once semen dries, the sperm within it become non-viable. Sperm can only survive for a limited time outside the human body, typically a few minutes to a few hours, depending on environmental conditions such as temperature and humidity. Once the semen has dried, the sperm are no longer capable of causing pregnancy.

In your scenario, if your boyfriend accidentally ejaculated on your leg and you wiped it off immediately, the sperm would have been exposed to air and the drying process would have begun almost immediately. After two hours, it is highly unlikely that any viable sperm would remain on your skin. Additionally, the act of rubbing your leg with another leg would not transfer any viable sperm to your vaginal area, especially since the semen would have dried and lost its ability to fertilize an egg.

Moreover, the concern about touching your vaginal area after having wiped your leg is understandable, but the likelihood of transferring any viable sperm from your leg to your vaginal area is extremely low. The skin acts as a barrier, and the sperm would need to be in a liquid state to swim and reach the cervix, which is not possible with dried semen.

It is also important to note that the "danger zone" or fertile window refers to the days in a menstrual cycle when a woman is most likely to conceive, which typically occurs around ovulation. If you are tracking your cycle and are aware of your fertile days, it is crucial to consider that the risk of pregnancy from the scenario you described remains negligible.

In conclusion, while it is always wise to be cautious and informed about sexual health and pregnancy risks, the situation you described does not pose a significant risk of pregnancy. If you have further concerns about your reproductive health or potential risks, it may be beneficial to consult with a healthcare provider who can provide personalized advice and information based on your specific circumstances. Additionally, if you are sexually active and wish to avoid unintended pregnancy, consider discussing reliable contraceptive methods with your healthcare provider.
