Yeah, people are different and I'm probably the strangest one.
Nahh, I don't do that either. I used to name the MC different each game, too. Then I started to get confused because I sometimes forgot my own name and was wondering who the NPCs were talking about. Now I name all my PCs Bob. It's the most generic name I could think of.
I still get confused sometimes though when there's an NPC called Bob. Maybe I should just call them Player.
In all seriousness though. I guess there are just different types of players. I myself realized that my habits kind of changed over time (mostly regular games, but I guess you could include adult games too). I used to try to generate a PC that was close to myself when I was younger and play that way too (what would I do in that situation?). Now I don't to that anymore, or at least a lot less than before. Actually, the more "foreign" (race, gender, behaviour etc), the better. By race I mean elves, dwarves etc, should the game allow it.
