Don't worry like that. You just got a bad partner, that's all. In any case, be sure to check with your doctor so as not to pick up anything. The chances of getting pregnant are minimal if he doesn't come inside you without a condom. Judging by your words, he took your virginity without a condom, and then continued intercourse with a condom. I think that he was simply afraid that his erection in a condom would weaken and he would not be able to deprive you of your virginity, and because of this he was nervous and did not pay enough attention to you.
