Bf can't make me ooh so good while having sex

we are already 3 yrs in our relatiinship and we have sex many times. every time we do it, he can't make me orgasm through my vagina. at first, i thought it was normal because i've read that vaginal orgasm is diffifuclt for some other girls. but now i talked with my friend and she told me that she always has orgasm even without penetration. when we have sex, i always like that he does the work and i do little. he comes too early that i can't orgasm. any thoughts?
