Can he cum inside you if you use birth control?

Cheyenne • Been with my man for 3 years ❤️ he's the one who told me to get this app so here I am! Hellooooo 👋🏼

I understand that birth control isn't 100% effective and there still is a risk. But someone told me that birth control is just to make it safer and you still have to use a condom? But I thought birth control is so that the guy can cum inside without pulling out?? Which is true?
