I am on birth control, and he always uses a condom, but we had a little bit too steamy of a make out session yesterday at the pool and there was no condom. Could I get pregnant?

This is my first guy I've ever had sex with, and I don't want to scare him if I'm just being a ridiculous "virgin". Lol
We didn't actually have full on sex cause there wasn't enough lube, but he said he almost cummed...
