Over all bigger is better works the same way with women as it does with men. You like ideal of a huge dik and men like the idea of huge breast and @ss, but in reality its more work than its worth usually. There are those out there that want or really like it, but on average its just a ideal visual.
getting a man to orgasm is simple stroke it and its going to happen, with a woman all kinda other things go into it. From mentally blocking herself from it, to only climaxing when "in pain" too the G spot being in some awkward location. Most women get off to clitoral stimulation more so than penetration anyway. And then there are those that get off to having there nipples suck are played with and anal. A big dik, banana,water bottle or whatever just makes the stroke job easier over all.
Aint nothing wrong with having a big vagina
But aint nothing like a tight wet one
