think about it from her point of view first.
this is THE FIRST time you've ever had a boyfriend, and you're excited.
perhaps, think back to the first time you dated a girl.
what were you like?
YOU, should actually be honored that she chose you to be her first boyfriend rather than other guys.
I'd say to give her some time to adjust to the feeling of having a boyfriend.
and because you're her first, i suggest you don't just suddenly break up with her.
put some distance between you two first and eventually have a mutual breakup.
therefore she won't be scarred for life, and get suicidal and never be able to trust guys again.
i don't know. i don't know how other girls think or react.
so just be careful and think about how she would feel.
and i absolutely agree that you two are at a honeymoon stage right now, so give it some time.
btw.
honeymoon stage means that you two are totally infatuated with each other and can't get enough of each other...for now. after a while, (once the stage passes) you'd start getting sick of each other...and this is the number one reason why teenagers break up after two weeks. their infatuation towards each other wears off. and when they no longer feel attraction, they take a 'break' or just end it and move on. a vicious cycle.
