But. Yes, there is a but. Sex doesn’t always go as planned and we humans are messy beings. So, your protective barrier may slip, break or simply be ineffective because of the material it is made of. This is why it is understandable to have a lot of questions concerning the use of condoms, especially if you are gearing up to have sex for the very first time. Remember, while condoms may be one of the best forms of birth control, they are not foolproof. It is QUITE possible to wear them incorrectly (or not wearing them consistently) and when you do that, you up the chances of getting pregnant.
