Let’s talk about sex

So I’m 17 and I’m in love with my boyfriend we’ve been dating for a while and I wanna have sex with him so bad and it’s not that we don’t have anywhere to do it’s that I’m terrified of getting pregnant because that’s all I heard from my mom that the only way not to get pregnant is to wait till marriage.

And I’m just terrified of having sex and then getting pregnant because I’m way too young but I know so many people that have a condoms break or something and I’m not on birth control.

On the other hand I know so many people that do use condoms and they’re fine. But I have no clue why am so scared of it.
