me and my boyfriend are starting to have sex. what are ways to avoid getting pregnant. my mom knows i'm having sex and refuses to let me start taking birth control and my boyfriend is completely allergic to all types of condoms, latex, non latex, and all of the other ones. we are both legally old enough and are both "mature". i just don't want to get pregnant and i don't know how to a avoid it. i know nothing is 100% and there is always a chance i just want to know some ways do reduce the risk. like anything to get in case i need it. things to do before we have sex and things to do during it.
