how to ask mother for birth control #sos

pud

hello friends^_^ im nervous abt asking my mother abt birth control so im going to rant a bit here♡ ive recently got a boyfriend (about 3 weeks ago to be exact) and we started becoming sexually active(oral), we havent had sex but i really really trust him and hes literally perfect so i wanna take it to the next step. i just dont know how to bring up birth control with my mother, shes chill and she wants me to be protected but im just so nervous abt it. im 17, my boyfriend is 18 and we have known each other and have been bestfriends since kindergarten, my parents absolutely adore him and has been talking abt us getting married since ive met him. im his first everything and has even admitted that ive been the only person he's ever truely liked :') . ive loved him since forever and i can spew abt him all day long :D he fulfills all of my fantasies and its literally a dream come true, hes so loving and constantly checks to see if im okay and oh tmi but he made me cum 6 TIMES!!!!! he even ate me out b4 i even touched his dick which is crazy to me! hes all abt pleasing me and hes literally perfect. okay this has turned into me just gushing abt him but how should i go abt asking my mom? should i say that i think i should get on birth control or should i say i want to get on birth control? should i say that i want to be protected incase we do have sex? i do realize we havent been dating long but hes always felt like home to me :)
