I've always seen Zevran from origins as very feminine, and Fenris from DA2 seemed kinda girly to me as well. Perhaps its the body type that gets me. But this is also very very subjective, what I think is more feminine and masculine could be completely different from what someone else might.
I've never really liked the BI options we've been presented with in the game until now because they never seemed masculine enough for me. I liked Anders because he was of a more thick physique? I'd rather we not have more feminine options since I'm desperate to actually be able to romance a guy my type as a male instead of having to play as female characters in order to do so.
I tend to agree with you, but I've seen a bunch of people on the forums say that not only are Zev and Fenris not femme, but they are too butch for their liking. While I certainly don't feel that way, I can see that it's really a matter of taste and that there is a market out there for femme guys and those stories aren't being told.
Speaking of Kaiden, does he count as a knight? I mean, personality wise, he's exactly what I think that sort of character would be like - plus his expressing his feelings was just cute. My first ME3 playthrough I ran my ME2 pure-renegade no romance Shep, and it just didn't occur to me getting Kaiden all his gifts would trigger his romance (and avoid ME3 forums so religiously I didn't even know he was available). So when he does his whole speech, I was kind of like... yeah, you know what, pure-renegade Shep isn't that averse to a romance after all.
Yep, I've mentioned this in the "bisexual" (their quotes, not mine) thread. I think Kaidan is the closest that we've ever gotten. The only thing that isn't quite right for me (and I'm just being picky) is that I'd love to see it played out in the fantasy genre, since that's really what the trope draws upon. That's why I want to see a true 'knight in shining armor' in the DA series.
Sidenote: While I've been thinking about this today, I came up with another knight from my childhood who I crushed hard on: Nicholas Clay as Lancelot in Exaclibur. God DAMN that guy made me swoon. And, of course, straight.
One of the things that's really hard for media to deal with right now is the discontinuity between personality and body type, too. Like, in terms of someone having a stereotypically aggressive, masculine and top-y personality but being built like Tom Cruise (or Colton Haynes from Arrow), or someone who's (to bring up an old fave), the bottomiest bottom who ever bottomed, but looks like Manu Benett (or, say, the Iron Bull).
Now how the hell am I going to find a way in my life to work in the phrase "the bottomiest bottom who ever bottomed"? <shrugs> I'll find a way, I'm sure!
