ok, i'm a traditional one, so i say, you are only 12 and you are stressing out about a kiss and relationships. you have plenty of years to think about this serious stuffs. anyways, the first kiss is i agree supposed to be unforgettable. but what if tyler also kissed another girl first instead of you, what would you feel? this is how relationships go, you don't just think about yourself but you also think about your partner. don't take relationships too seriously at your age, as the other comments say, you still have a long way to go. Thanks!
