Don't feel bad
It really does happen to others- trust me, I would know. Sometimes, when I think of the person(s) who abused me, I can't help but be aroused for some reason. I can understand the confusion and the feeling of being "dirty", or feeling disgusted. I can't tell you WHY it happens, but somewhere along the way, some people become "conditioned" per say; that is to say, when certain conditions or situations arise (a smell, or a memory, or anything really), something instinctual rises and causes stimulation. I get that way sometimes too, when I think of my father and my ex-boyfriend (if that is even the right title for him).
