waiting until marriage to have sex or kiss

waiting until marriage to have sex or kiss. i didn't really concern this when i first heard it, because i kissed already but the sex part was bugged me. i mean i don't know if i'll get married when i'm 20 or 35 ya know...that's scary. that was how i thought about it when i first heard to do that in which i think i was 15 or 16. i've broken that rule of God when i was 17, which i regret. i regret it because i wasn't being wise and responsible of giving my wife a pure body. And before i get married i have to tell the woman i'm going to marry that i'm not a virgin, i dont know if it'll will hurt her or not but i hope it doesn't.
