Can I prevent pregnancy by doing these old wives tales?
The only way to prevent pregnancy 100% is by abstaining from sex. Even birth control isn’t 100% effective, so I always recommend for 2 different types to be used. When you’re in a casual relationship condoms are a MUST because you don’t want to contract a STD as well as getting pregnant. Soap won’t stop sperm from getting to your eggs, it doesn’t wash it away at all. If anything it pushes them further into your vaginal canal, it will not kill them either. They can still live for up to 24 hours inside of you without making it to an egg for fertilization. Also, while some lubes have been said to reduce sperm count it will not stop them or slow them down. Especially a water or silicone based lubricant.
