I've been with a number of women, and I've made them all cum...usually it's just finding out where her spot it, or what she likes, and doing it, then you'll make her cum...that's what I find....it's a search and find thing...Now the girl I'm with now, she was with bigger than me, and with smaller, but she is multi orgasmic and on a regular night will cum 7-8 times...now she says she never did that with anyone, she says my size is perfect for her, it fits inside her just right...Now that is according to her. She has been more experienced with bigger dick than most of the other women I was with, and if she feels that way, maybe it isn't how big or how small, but just being that right size....
