Has anyone taught themselves to orgasm with their partner from not being able to?

I have been with my parter for 3 months and we have been having sex regularly in that time. He is the first person I have had penetrative sex with so it took a while to get used to but now we can do everything and anything and have amazing sexual experiences together. Sex feels incredible to me - like unbelievably pleasureable but I just can't cum from anything he does. The foreplay is great, he lasts a long time, he stimulates me in every way imaginable and we try all sorts of positions and are never shy in any way with asking each other for what we want. I can orgasm when I masturbate and have been doing so for years but can't with him regardless of all the things we try. I've read about so many women experiencing the same thing but what I really want to know is if any of them overcame that? Should I have hope?
I enjoy sex without orgasming and my boyfriend never pressures me but I don't know if this is just another hurdle and if I should be working on my own to orgasm internally to help? Or should I wait and maybe it will come naturally? 
I really want to share this experience with my boyfriend. 
Please let me know if you've overcome this yourself. 
I'd appreciate any advice :)
