the influence that a female exerts over the male, either by using sex, the stated, or the unstated prospect of sex(regardless of her intention to actually have sex with him). Similar to being "pussy-whipped", but without the prerequisite of sex (although there may still be sex).
"Dude, why did you go see the new twilight with her?"
"It's that damn vaginal pull! I know she isn't going to have sex with me, but I cant say no"
