Sexually frustrated??

My boyfriend and i who have been together for almost two years have sex on a daily basis. Except my special week when mother natures in town then its about 2-4 times that week. Anyway he pleasures me very veryy well so i know its not that he doesnt pleasure me correctly but is it possible for my to be sexually frustrated.. I just feel like i dont get enough and we normally have about three to  five rounds daily .. Around eight on a good day
