No sex....really hard!

Hi....all im gonna say is that im 14 soon  to be 15....my boyfriend is 17 and we have been dating for 4 months and 3 days
(I love to count).....anyways i understand that some teenage girls are having sex at a younger age but i dont really wanna be like them(no offense to those girls)
I do wanna wait and so does my boyfriend, but its abit hard, we're both sexually attracted to one another really bad. He understand that im not fully mature yet and so is he(boys technically stop puberty at 18) i heard stories saying that waiting can be rough and hard along the way but that you receive a great reward of love at the end....we want some advise and tips, how can we make it easier to not be so sexually active, we're both virgins.
