The strange thing is that I find it hard to label any of those people "fucked up". They all appear to enjoy it, and they certainly have choices to make. My friend, for example, LOVES sex. She cannot get enough. She will tell you how awesome it is to suck off a complete stranger on a bus. Now, did she end up that way because she was molested or would she have turned out that way anyway? She will outright deny that trauma is compelling her to behave in inusual ways, and again, by all appearances she certainly does seem to love it.
