I used to totally feel that way when i was your age.
then when i was 17 God let me have an online relationship with a guy. I think God let me have that relationship just to shut me up! lol. anyways the guy was nice, but after 6 months we both decided it wasnt worth it and broke up.
I'm 19 and i am still waiting, and i realized that dating isnt worth it unless you are ready to marry. cuz i mean when you are young, you get a guy, and then what? sure couples keep dating for years and years and it sometimes works. but most of the time the relationships fade.
so dont worry! God will send you the right guy at the right time! =]
and dont feel guilty! if it makes you feel less guilty, pray for your future husband! pray for God to keep him from harm and keep him pure. I know i pray for my future husband, whomever he may be.
