Yes size matters. My hubby is nowhere near big enough to make my cum alone. He usually has to use a toy on my clit or a toy to fuck me with in order to get off.
I wouldn’t say better but more exciting also. Before i knew he was into this lifestyle i would go out on him while he was away and i would get some on the side. I guess what also made it better was the suspense of getting caught.
There has been many of times i have come home full and my hubby have no clue till i was sitting in his face and could taste it or have his dick and me and could fill the cream inside
