I've dated a girl for awhile but the day we kissed each other it felt like the world stopped for hours even though it was a couple of second and besides it felt like my stomach was crushing itself later on. Is that good:) or bad:(.

That's Good! Stay cool and don't rush into anything! Enjoy yourself! Nice to see there's still people that get butterflies from kisses...

Now if this is the girl from your other post (which I'm sure it is)... FOCUS ON SCHOOL! Haha

Yeah its good... but too soon to tell... it might just be the initial excitement... so listen to Troy and take it slow and see where it leads... don't start telling her she is the one just yet... might freak her out...
