Does my boyfriend need to pull out if I’m on the kylenna coil?

No, the coil is extremely effective at stopping pregnancy and even if he does pull out, pre-cum fluid can contain sperm

Pull out does nothing. Pre-cum contains live sperm. If you’re in a situation where you are unsure you should use condoms. If you’ve waited until your IUD is in effect then it will protect you from pregnancy.

No he doesn’t the same goes with any birthcontrol after you are protected against pregnancy when first starting

But can’t some birth control fail

Only from user error and a very very very small percentage of women have a genetic condition that causes birthcontrol to fail. But I mean very very very small chance

@McKaka the IUD is one of the most reliable methods.
