Which birth control?

Olivia
Im 14 just about 15 (if your gonna start judging about how young i am please stop reading now) and i really want some kind of pretection other than condoms. Yeah id still use them but i need something else to. Plus the pill i couldnt keep up with. Im thinking about the IUD but i dont know if i can get it at my age and some people say the strings or what ever poke the guys dick sometimes durring sex? So idk what one i should get. Also say if i got a bf at some point that i really trusted and we both went to a clinic and got tested and we were both clean. Would it be okay to try sex without a condom like once because i wanna know what it feels like.
