Am i even orgasming ...?

So, when I masturbate I orgasm, but it feels completely different to when my boyfriend fingers me/ eats me out. I don't seem to reach the mind blowing moment, I just sort of feel a little spark then get sensitive and pull away..
I always get turned on, and we've tried different speeds, different ways, just the clit/fingers 
Nothing feels the same as when I'm alone ..?
