could I get pregnant ?

I am a virgin my boyfriend and I were turned on and we were humping each tiger until we took our clothes off and he rubbed his penis with my vagina for a while and then he precum and cumm on my stomach then we stopped but then an hour later we were humping each other and the same thing happened but then idk i'm scared if the pre ejaculation or precum could affect the possibility of being pregnant again he didn't get inside me i'm still am a virgin
