I don't know, there's a lot of canon evidence that points towards the fact that Dean probably wouldn't be all that surprised to find out he was bi. I don't know if you watch the show really, since I saw your comment in your journal about the acting being sucky, but Dean has actually used his wiles on a guy before in order to get what he wanted, and there's a part in Phantom Traveller where Dean's on a plane walking past a guy with his headphones on. The dude looks up and gives Dean a pretty lecherous look and Dean just sort of smiles a little and continues on. I don't think it would really bother him, to be honest.

I...am babbling. Pls just stop reading if you don't want to hear me go on and on and on about Dean's character.

Personally, it seems to me that Dean is less interested in relationships, and more interested in just getting the hell off, and soon. They're constantly on the move, and have been ever seen Dean was really young. I can imagine that early on, he tried to have regular girlfriends, he tried to play the normal one, but he just had too much responsibility and too much dedication to (his father and) the cause.

And, well, he already loves Sam, doesn't he? It's pretty hard to even attempt to see it otherwise. Sam's the most important thing in his entire life, especially after John goes off on his own and Sam spends an entire year by his side. I can see that VERY MUCH messing with Dean's mind, having that one constant presence, who he loves so so much right there.


...i'm gonna shut up now.
