I don't think your a freak at all! We all have deep dark fantasies that are just that, fantasies... if you want to make it a reality, that's between consenting adults isn't it? I think that when it comes to fantasy and/or living out fantasies that we tend to push the envelope into taboo in order to find excitement or that 'high' that comes from something new different or naughty. I beleive that so long as your not forcing someone to do something they don't want or violating a child (who can't form the requisite intent to engage in sexual activity) you are free to do anything you can dream up. No harm, no foul in my book!
