Pajeet discusses how women get aroused

Use your tongue~

First, the vagina is pretty elastic. When women become aroused their vaginal canal can elongate to accomodate many sizes, then will shrink back down. In my personal experience and experience from playing with women, using a big dildo is not going to lessen the amount of pleasure a woman would feel from a normal sized dick(if she's properly aroused)...I've found it can increase pleasure. All toys increase blood flow but big dildos stretch the vaginal walls, so when they're removed there's a rush of blood to the area causing the inner tissue to engorge, making it more sensitive, receptive, and juicy. But this may not be true for all women
