race v sexuality

i'm so busy lately that i rarely have time to gather my thoughts and reflect appropriately. some background for you: i have been taking a women's sexuality course. it's been interesting and mostly biologically focused, but it has been all-in-all pretty swell. however, i've been thinking about the differences between the sexuality of a white woman and that of women of color. i have absolutely zero experience or true insight into the sexuality of white women, but for some reason i believe a difference might exist. and, i don't mean in a biological sense. purely cultural. is there any truth in this? i honestly don't know. i'll post something up if i find anything supporting or refuting my argument.
