Im 18. why does it take me so long to have an orgasm with my boyfriend ? i do masterbate, is that a problem ?

Orgasm: Having an orgasm involves multiple factors that include both physical and psychological stimulation. Performance anxiety, and the simple fact that you think about not reaching orgasm in a timely manner can affect your ability to do so. Try discussing this with bf, and or experimenting with different sexual activities to stimulate and arouse you differently. A sex therapist can be helpful too.
