finally having sex!!! (birth control & sex talk)

so i'm dating this AMAZING man and we both really feel ready to have sex. the thing is, we're both virgins, and i won't be visiting my doctor about birth control until AFTER we have sex for the first time. however i don't know if i want to be on the pill because i don't want to risk getting pregnant AT ALL 🙅🏻

so i'm thinking and getting an arm implant since we're both in our 20s and definitely won't want to have kids for quite a while. that, or the nuva ring but the idea of sticking something in my no-no square sounds uncomfortable since i don't even like to wear tampons?? has anyone here used both or either? pros &cons;?

we're also obviously using a condom but because he's never really used one before, should i like, give him a bj with it in first? i'm sorry if this is a stupid question i just don't want it to rip and if it's the wrong size i want to make sure BEFORE he sticks it inside me!

thank you guys!!!
