unprotected sex

so i just wanted to like start a discussion because i had some questions and i also just wanna hear what others have to say. so i wanna start by saying i’m not on any form of contraception like birth control. i have this new boyfriend and we have had sex like 4-5 times... the first time we did it with a condom because before him i have only had sex once. after a while he convinced me to take off the condom and i agreed. every time since then we have had sex without one and i’m kind of getting worried. on friday, we had sex and he came in me a little and i got the morning after pill but i’m still like worried because i haven’t gotten my period and i’m worried i won’t, although i’m not due yet. today we had sex and i told him to use a condom and like 1 min into it he goes i can’t feel anything so he took it off. so... all i’m saying is, does anyone else not take birth control and do you use protection? should i start forcing him to use a condom? can you get pregnant if he cums on or around your vagina ?
