The white females I have dated varied in the derriere dept. but, c'est la vie!
My comments were aimed at saying : if you are flat, flaunt it! If you bertha butt bootied, flaunt it!
Every size, booty or tits or hips or lips can be erotic in the hands of a connoisseur like myself. Analingus, rimming, thumb plugging, licking, sucking and kissing (with hygienic, cleansed and douches bungholes) can be foreplay for awesome anal or clean up for raunchy afterglow. .... Yes! Feel like I wanna testify! !!
