is it possible to cum without feeling it?

Okay so I'm 17 and I'm sort of in the position where my parents have no idea that I have sex and can't find out because I'd be in such deep trouble, but yesterday me and my boyfriend had sex(protected) and he kept asking me if I cummed and I honestly did not feel it if i did and he pulled out twice to check the condom and it wasn't broken or anything. He sometimes has a habit of cumming in the condom while still in me but he said this time he pulled out before he came(and he came a lot) is it possible for the cum to go out the side? Also for girls to cum and not feel it at all? and I don't know if I should get a plan B or not to be on the safe side but I'm sort of freaking because I cannot get pregnant and we did have safe sex 😪
