What Are The Risks Of Having Unprotected Sex?

this isn't really a health question but me and my boyfriend were at a party last weekend. we hadn't been drinking and we had never had sex before because we didnt want to rush anything. we really love each other and he said he wanted to go up to one of the rooms to show me how much he loves me. i wasnt sure but i went anyway. when we got up there, we started kissing and touching, and then he started undoing my dress. i told him to stop and that i love him but i want to wait and he started to get really angry. he satrted kissing me even harder and then he locked to door. i was getting woried, but i didnt think he'd do anything to hurt me so i kept kissing him until he put his hand up my dress. i told him to stop, but he pushed me onto the bed and got on top of me. the music was really loud and everyone was downstairs so there wasnt much i could do. he took my dress off, then his pants. he kept saying he was "sorry to do this" and that he was sick of waiting but he did love me. he was kissing me and my boobs and then he put his penis in my vagina. i was begging for him to stop, but he wouldnt. he was doing it really hard and then after he fingered me until i had a squirting orgasm. he didn't use a condom or anything and now im really worried. please HELP???
