1. I am not a sadist, but my emotional logic is such that it is a whole lot easier for me to deal with a relationship if it involves and is founded around pain and suffering, within the limits of pragmatical borders (that is: MUST NOT INVOLVE KILLINGS, MUTILATIONS OR GOVERNMENTAL AGENCIES). Also, dominant aggressive rigid compulsory obsessive controlling women are super attractive.
2. I wouldn't mind at all if a 'real' woman by some miracle had a penis. However, if you are born female it is absolutely impossible to occur naturally or by technology. Men now acknowledgeable as women by their own choice will always turn out to be men with gender identity issues in my perception. If it is by chance and lucky genetics not merely for the obvious physical differences, it will be so mentally and personality-wise. I have actually bumped into that problem quite often. The more you get to know a person beyond their social self-image, the more difficult it will be to not see past it. I would be gay if I could, but sex drive is beyond my control.
