AITAH for not wanting to get an IUD

My boyfriend (19M) and i (17F) have been dating for 3 and 1/2 months and had sex already and first when we did it he took off his condom without telling me but i was too shy to say anything. He does pull out so i didnt get pregnant but i dont want to risk anymore. He doesnt want to wear a condom because he claims that he "feels nothing with it" and once even went soft when trying to bave sex with it on with another girl he dated before me. Hes trying to convince me to get an contraceptive inplant thing in my arm but i am scared of the side effects and dont want hornones rushing through me and it just doesnt look nice and ive heard is pretty painful. But hes really presssuring me to get it and when i told him that he should just wear condoms he was like: "so you want me to just not feel anything"and he said that the responsibility is on both of us if I get pregnant but our dialog didn't help anything cause we are stuck on that he doesn't like condoms and "is not going to wear one" and I am scared of the side effects and stuff from contraceptives. And the responsibility is again not: "on both of us" if i would get pregnant right now I would most likely get an abortion because I'm in no shape to be a mother so it would again go over me and not affect him in any way and he just doesn't get it. I know I'm being petty and I get that it probably doesn't feel as good with a condom compared to doing it raw but in my mind that's a better solution than contraception that I'm not ready for. All I've heard is that it hurts and there are a lot of side effects, but I can understand why he wants me to get but I'm just not ready for it. How can condoms be that bad that he just goes soft and im still mad about him taking off his condom the second time we had sex without telling me. I don't know what to do and he just keeps telling me to stop procrastinating and just get the contraceptive thingy in my arm but I'm scared and think that he should just swallow his pride and use a condom cause like we don't want a pregnancy and even less an abortion

Edit: I'm extra worried about hormone things cause my mom has REALLY struggled with them and I just dont want to also go through that
