Well, I don't have any scatalogical fetishes, but I do consider myself to be oriented toward fetishistic behavior. I don't think of them as *sick* but some people might and I think that is all relative. I am a female and I am a sexual submissive. I like to be pushed, pulled, forced, used, spanked, pinched, raped and otherwise frightened and, to some extent, humiliated during sex. With varying degrees of intensity - meaning, I don't always need a high-powered intensive D/s session to get off during sex - but even with more "traditional" sex, when we are engaging in more traditional, balanced sex roles, there is some element of D/s in there...even if it's just in my head. Luckily for me, I have found a man to corrupt into playing a dominant role with me in bed.
And he has adopted the role with
mucho gusto, lol.
As for where this came from, I honestly cannot remember a time (post discovering masturbation) when I didn't have fantasies of being sexually dominated. I have no idea where it came from. The obvious cause could be that my mother left my father when I was young and I went through most of my years growing up without a steady father figure in my life. That could be it...but it doesn't feel that way to me. If anything, I feel it's more closely linked to an intense shyness that I had as a child. I can't say how, but I think somehow it evolved out of that...combined with my fascination with Captain Kirk as a very young child. Seriously. I think in the primal scheme of things, I am just a submissive animal. And I am turned on by being the sexual object of an animal who is more powerful.
Using the word "object" calls up another fetishistic aspect of it which is considerably more difficult for me to admit to and talk about and that is the concept that I am, sometimes, not an autonomous person of freewill, but a sexual object to be used completely at the whim of another. Having someone to safely express this aspect of myself with is incredibly exhilarating. And by safely, I mean, with someone who handles the responsibility for exploiting it with awareness and discrimination and who respects that this doesn't carry over into my life at large. After all, I am quite a determined and individualistic sort of person when all is said and done. I used to not be so, but I have no intention, at this point in my life, of being pushed around or taken advantage of.
I also have other fetishes...stockings, corsets, bondage...it's all tied together, though, no pun intended, heh heh. The thing that's kind of significant about my stocking fetish, is that I never considered my interest in stockings to be a fetish (it was always more of a fashion thing for me - sexy, yes, but not fetish-y) until I met someone who has a bonafied stocking fetish. Now, stockings have a whole new sexual relevance for me. Seeing pictures of them - especially a garter cutting into soft flesh or the way they wrinkle around where the garter attaches to the top of the stocking, putting them on, snapping the garters, seeing the way he reacts when he caresses the spot where the top of the stocking meets the flesh of my thigh or when he tugs on the tops of them while we are having sex...all this has brought a whole new fetish-y significance to my appreciation of stockings. I guess I am very suggestible when it comes to some fetishes...especially where the fetishes of my dominant partner are concerned. I can't say for sure where my hard limits might be if he expressed a desire for something...other than no animals and no children, yadda, yadda, yadda...
I don't know if this addresses the OP, but I don't get a lot of opportunities to yap about my proclivities...I think it does me good...and ratbastid and abaya asked.
