boys have to pay attention in sex ed

Today I had sex for the first time in a couple of weeks. It wasn't that good, he kinda had to finish me with his hands, he kept talking, it just wasn't a fun time for me. But the first time, we had sex we used a condom, that's okay and safe. We laid down for a while and he asked if he could go again without the condom. I told him I didn't really want him to because I didn't want to risk it. Then he later went in raw for a little bit anyways before putting on the condom. The chances are low and I know it, but I still have concerns and I know the stress will cause my period to be later and that'll scare me even more. What should I do? This stuff has happened before and it's always turned out okay but it always scares the living hell out of me.
