Pulling out

I keep seeing people saying about pulling out and not wanting to be pregnant, I personally think if they use the pull out method they should be ready if they do get pregnant and ready for that chance to happen but if they are not ready for a baby and know they would have an abortion ect I think they should use more than pulling out like birth control or condoms but should know that still isn't 100% and if they can't handle that don't have sex at all
