how do i give him good sex?

or make him want me when hes so used to me now that my body, whatever i wear, or whatever i do sexually doesnt even turn him on anymore. unless he wants sex. ive done google search, a majority of them just say to wear lingerine or show off skin cause guys are visual creatures, but like i said, hes so used to me now that even if i were to do those things, it doesnt turn him on or make him want sex anymore. sigh, but i bet if it was a new woman, hed get turned on.
