In many films and serials devil, demons, ghosts and etc. use to possess primarily women. Vampires may me added here. Somehow I find it attractive: long time ago I got aroused during watching some cartoon, where some 'evil' possessed woman and she got changed when I was very little boy and got really confused, because did not understand what was happening to me.
Noting really changed with age. I would not be mind the very fact of it, but it does create some problems in sex sometimes: I feel I need something of that 'mystery evil' to get really excited.
My own assumption is that problem in uncertainty in myself: some supernatural stuff should happen to female to get her really excited to me. I am young healthy guy, making some successes in job and I have wonderful girlfriend, and we love each other. I really want to learn a nature of this problem to solve it. Thank you for attention.
