Is it normal that I can only have one orgasm?

Im only a 14 year old girl so obviously Im still a virgin so I use masturbation to get myself off. Well I never fail to achieve orgasm, but the problem is after I have one orgasm I'm just spent and not really interested in masturbation for the rest of the day. I know most females have multiple orgasms but after my first orgasm I can't be coaxed back into arousal by touching myself and I kinda just lose the mood Im in. Is that normal, because I heard that females are supposed to have multiple orgasms in a row when they masturbate?
