my boyfriend and i had sex for the first time and we had a long time just to put his penis inside me because i was really tight and when he finally inserted his whole penis inside me, he decided to stop what we are doing because he sees that im in pain, and i admit im in too much pain , he does not even pushed in and out of his penis inside me. when i asked him if he ejaculated inside me or cum a little bit, he says he's sure that he's not. but im still afraid. we're not using condom is another reason why im afraid. answer please help me :( im 17 years old.
