Preventing pregnancy can be a tricky business, especially when you're trying to get down to business. Bustle mentions that there are some old wives' tales about preventing unwanted pregnancy that are just flat-out not true. Avoid these at all costs!

  • Two condoms are more effective than just one is so far from the truth because using two condoms is almost like not using one at all. Friction between the two layers of latex can cause both of them to break.
  • Standing up while having sex because the sperm can't swim up... that defies gravity! Gravity is not a form of birth control.
  • Having sex while you're menstruating might seem logical, but there are so many factors involved (including the fact that sperm can survive for three days) so it's a risk you just don't want to take.

Sex is complicated! It can be a lot of fun, but in also involves a lot of risks (STDs included) that you may not always be ready for, so be safe every time!
