unprotected sex, shouldn't be too worried?

On New Year's <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, I lost my virginity to my boyfriend. We used a rubber but every time he put it on he went soft. I was still a stickler and we tried the whole sex with a rubber but it was meh. Eventually we ventured into a realm of without a condom, (he didn't ejaculate, I did. Any precum that might have sperm shouldn't because the night before he masturbated to "last longer" and he pees a ton so,) and anyway it was the BEST šŸ˜µšŸ˜µšŸ˜
But the moral of the story here is I'm not too worried about getting pregnant, and is it right that I Shouldn't? Obviously if it was any other day, or any other circumstance I would be so worried, but because he didn't cum, I'm really not. I'm going on Birth control asap, and this will never happen again...
BUT IS IT OK THAT IM NOT WORRIED. šŸ¤”Ā
