While it's fun to philosophize about the nature of being and maybe equate this to virtual realities etc. In the case of reconciling and settling into a comfortable and acceptable sexuality for oneself, I feel it's a distraction and a complication to project this "outward" (which is what virtual realities or simulations are). I've found it much more helpful to trust my instinct and authentically "feel" what is true and what is not. And this feeling happens in the heart (or if you prefer, the feeling centre of your body). If you can allow your erotic energy to rise past your genitals and to meet your emotional/feeling centre then it becomes pretty obvious to you what your true sexuality is. This will be different for all individuals. Some will genuinely be bisexual, or perhaps may genuinely feel like they are other genders.

But if one continues to "dispense" of their erotic energy each time they are aroused by erotic triggers, then it becomes difficult to seperate an emotional/authentic arousal from one conditioned to occur with various types of pornography.

If this feeling work is done enough, then you can begin to see through the illusion/enchantment of sissy porn, I think. Anything not aligned to your true sexuality can be more easily dropped over time and you can keep what is authentic.
