The probability of pregnancy when the penis comes into contact with the external genitalia?
Based on the menstrual cycle dates provided (11/28-12/21 and 1/1-1/5), the estimated ovulation period is today or tomorrow.
There was one instance of protected vaginal intercourse (with a condom) today, with no leakage or spillage.
Additionally, there was one instance of unprotected anal intercourse, during which the penis made contact with the vulva but did not penetrate; it was immediately withdrawn upon contact.
Ejaculation occurred in the anus, and there was no leakage afterward.
You are concerned about the possibility of pregnancy due to the contact with the vulva.
While the risk of pregnancy from this scenario is low, it is not entirely absent, as sperm can potentially be present on the skin and could lead to pregnancy if it comes into contact with the vaginal area.
If you are worried about the risk of pregnancy, consider taking a home pregnancy test if your period is late or consult a healthcare provider for further advice.

When it comes to the question of whether rubbing against the vulva can lead to pregnancy, it’s essential to understand the mechanics of conception and the risks involved in sexual activity. Pregnancy occurs when sperm fertilizes an egg, which typically happens during vaginal intercourse when sperm is deposited in the vagina. However, the scenario you described involves several factors that need to be considered.
Firstly, the act of rubbing against the vulva, also known as external genital contact, does not directly lead to pregnancy. For pregnancy to occur, sperm must enter the vaginal canal and reach the cervix, where it can then travel to fertilize an egg. In your case, since there was no penetration and the penis was removed before ejaculation, the likelihood of sperm entering the vagina is significantly reduced.
However, it’s important to note that pre-ejaculate fluid (pre-cum) can contain sperm. If there was any contact with pre-ejaculate fluid on the vulva, there is a very small risk of pregnancy. This is because sperm can potentially travel from the external genitalia into the vagina, especially if there is any fluid transfer. Nevertheless, the chances of conception from such contact are considerably lower than from direct ejaculation into the vagina.
In your situation, since you mentioned that you used a condom during the initial sexual encounter and that there was no ejaculation inside the vagina, this further decreases the risk of pregnancy. Condoms are highly effective at preventing both pregnancy and sexually transmitted infections when used correctly. However, if the condom was compromised or if there was any failure in its use, that could increase the risk.
Regarding the anal intercourse that followed, while it does not directly involve the vagina, it’s crucial to understand that if there was any transfer of sperm from the anal area to the vulva, there could be a theoretical risk of pregnancy. However, this scenario is quite unlikely, especially since you indicated that the penis was removed before ejaculation.
If you are concerned about the possibility of pregnancy, it may be beneficial to take a home pregnancy test if your period is late or if you experience any unusual symptoms. Additionally, if you are sexually active and wish to avoid pregnancy, consider discussing reliable contraceptive methods with a healthcare provider. Options include hormonal birth control, intrauterine devices (IUDs), and barrier methods, among others.
In summary, while the risk of pregnancy from rubbing against the vulva, especially without penetration and with the use of a condom, is very low, it is not entirely zero. If you have further concerns or if your situation changes, consulting with a healthcare professional can provide personalized advice and reassurance.
