How Effective Is Birth Control If My Partner Cums Inside Me?

While birth control is never 100% effective, some types are better than others at preventing pregnancy if your partner cums inside you – whether intentionally or accidentally.
- You can get pregnant even if you are on birth control. In addition, NO birth control is 100% effective.
- You are more likely to get pregnant if your partner ejaculates inside you, however, pre-ejaculate (precum) can contain live sperm that could lead to pregnancy.
- Long-lasting birth control methods like the implant and the intrauterine device (IUD) are the most effective (over 99%) because they remain in place, reducing the risks associated with imperfect use — such as forgetting to take a daily pill, for instance.
- Birth control methods like the pill (99%), the shot (99%), and condoms (98%) are more effective when used exactly as instructed. However, due to inconsistent or late use, their average efficacy is only 93%, 96%, and 87%, respectively.
- Combining birth control methods (such as using a condom while also taking the pill) can reduce the risk of pregnancy even if your partner cums inside you.
- When you begin or end a particular method of birth control also plays a role in your risk for unintended pregnancy.
There are many ways to avoid pregnancy, including birth control, condoms, spermicide, the pull-out method, and tracking your ovulation cycle.
Some people use various combinations of these birth control methods, while others proceed with a wish and a prayer.
While we don’t recommend taking a “fingers-crossed” approach to pregnancy prevention, we do understand that sometimes you just want your partner to cum inside you when the going gets good – or it might happen accidentally (if a condom breaks for example).
So, assuming your partner is male-identifying, can he finish inside if you’re on birth control?
The short answer is maybe – as it depends on a lot of factors.
