I consider myself a switch.
I feel that there are three different categories when I encounter the BDSM scenes and scenarios:
I. Those that I like to read/see and experience myself in the real world as well (of course after all the essential criteria are met)
II. Those that I like to read/see and imagine them in a fantasy but do not like to actually happen in the real world.
III. Those that I hate to read/see or even think about the possibility of imagining them.
I try to find ideas about the first and second categories here on Literotica, and if I accidentally encounter a third one, I just close the page and go away.
