If I were to guess, I would say that condoms are probably the most popular form of birth control out there. Why? They’re easy to access (you can buy them almost anywhere, regardless of how embarrassing it might be), they’re easy to use, you don’t need to see a doctor to get them, and they’re inexpensive. And when it comes down to it, condoms are also one of the best forms of birth control because they prevent against both pregnancies and most STDs. Other forms of birth control, like the Pill or IUD, only protect against pregnancies.
