No, they don't freak me out, because I have fantasies like that all the time. I write erotica with those exact themes as well and I read a lot of erotica with those themes. Just because you write or read something doesn't mean that you want it to really happen. This erotica is fiction and fantasy. Not real life. So please keep posting your stories. As others here have said, if someone doesn't enjoy them, they don't have to read them. But there are others here who do. One thing I have learned from years of writing: never censor yourself, because when you do your writing suffers and suffers badly. So silence that internal critic and keep writing!
