I am not sure how much arousal carries over for my wife. Sometimes my wife does not seem to be real aroused, but is going along with my rubbing to get myself off. Sometimes I feel that I should have taken more time to finder her clitoris and he vagina to get her more arouse for wet vaginal sex. Sometimes my wife seems happy in the morning, going to work, without having gotten off. Sometimes it carries over, and I find her receptive the next night. So I work longer to get her more aroused, and keep going till she is ready to have vaginal sex. Sometimes I wonder if, like me, that my wife might be thinking more about sex, if I don't have vaginal sex with her, and get her off. I have found finger guards, miniature rubbers, make my fingering her vagina more pleasant for her. Gets her hot better. I don't keep my finger nails real short. .
