I feel discouraged :/?

Don't really know why i'm worrying about this now, i'm just fifteen. But i'm staying a virgin till marriage. This isn't because of religious purposes though i am a christian. i just want to ultimately give myself to Tthe one i want to spend the rest of my life with(cheesy much xD?). And i think the best way to ensure this is not to date during high school. just have girl and guy friends, which i'm alright with :). but when i hit college (more like midway college) and i want to begin genuine relationships, i'm sort of hesitant. Do you think they will be more respectful of my choice? not that someone in high school wouldn't, but i hear they mature or something lol. what are your opinions, and if your male and out of high school, please have an input, k, thanks :).
