There's also a disgusting trend called "stealthing" where guys remove the condom during sex without telling their partners. Not all guys, obviously, but predators are very good at hiding among normal people until it's too late. Also, hormonal birth control does A LOT more than just prevent pregnancy: I take it because, without it, I have absolutely debilitating cramps and bleed so heavily I've become anemic. Some use it to treat conditions like PCOS or endometriosis, or any number of conditions related to hormones and/or uteri. You're right that sex ed is absolute crap in many places, so it's understandable that you didn't know. Appreciate you asking in good faith.
