You’re very welcome, friend. 🙂
I do have to admit, my aro headcanons are a bit self-serving. I’m aro so I like to show some of my favorites as aro in fics and headcanons. (Partly because people tend to understand concepts better in fiction so if they see Dean or Sam or Cas as aro or ace or on the a-spectrum(s), they’ll understand it better.) So yeah, ace and aro headcanons and representations of characters are important to me. 🙂
I tend to see Sam as pansexual demiromantic, but demisexual demiromantic or demisexual panromantic totally works for me, too. I would definitely agree he has issues with sex and romance, though. And I think that can be born out in canon as well because he’s kind of apathetic about sex and romance. Like, as much as people seem to see Sam as straight, I kind of don’t. I don’t see him really caring about the gender of his partners. It kinda feels like a default assumption to me, to be honest. He just isn’t that comfortable with romantic advances and he’s not nearly as anxious to sleep with people as Dean is. So, yeah. Sam, in my mind, is definitely on the a-spectrum.
I’m glad you like to see these headcanons, though. And I’m always up for talking about them at any time. 🙂
