Definitely spoilers, with regards to romance stuff.
Long story short, for a quick reference, check out Game Theory's channel on Youtube regarding LGBT and video games.
So... I'm glad they included "straight" gay characters (haha, get it?) in the game. I actually think that's really cool. However, I object to how they're depicted. They're both effectively stereotypes, or deviant. Something similar happened in DA2. In fact, it's a trend in gaming's depiction of homosexual people in general. In mainstream video games, gay people tend to be shown to be "different," as opposed to just people who happen to be gay.
I play a "whatever-sexual" male elf who flirts with everyone at every opportunity, for some background...
Now, I haven't completed any of the romances, so this observation is just based on where I'm at in the various courtings. I'm at the point where I've got a choice to enter into a relationship between Dorian, Josephine or Cassandra. Here's what I mean about the gay relationships in Dragon Age 2 and Inquisition being wrong:
Let's start with Cassandra. At first, she's somewhat cold and doesn't respond to flirting well. Eventually, you need to try to woo her with gifts and doing your man-thing, trying to get the girl, so to speak. You have to "work" for her affection. You can't just say, "Hey, I like to flirt with you, and I may want to have a relationship" and have them just latch on to you.
Same thing with Josephine. If you want to get with her, you need to defend her life one way or another against some assassins. It takes time and effort. There's the actual building of a rapport.
Leiliana, a bisexual character from Dragon Age: Origins, you do something similar. You have to confront her past, protect her life, say nice things, give gifts, etc.
In my opinion, these are fairly well-written, in a Bioware sense. However, the gay relationships are ridiculous. Let's do a quick review of the relationships and the type of people they are:
Cassandra - Strong, passionate about justice, tough on the outside, soft on the inside. Romanced by treating her like a woman. Requires the protection of her life to romance.
Josephine - Exotic, comes from nobility, has integrity, has a little bit of a school-girlish demeanor when it comes to relationships. Requires the player to play the hero and protect her.
Leiliana - Again, strong, different, kind of special, secretive, talented, caring, romantic. Requires protecting her life to romance her.
Seeing a pattern? Ok, let's move on to my problem, finally.
Dorian - Quirky, sarcastic, funny, antagonistic, comes from a place most consider "evil / bad," rejects his family's intentions. Flirty. Romanced by finding out that his dad has a problem with him being gay. Mention that you think that's great in a flirty way and suddenly you're all over each other. If this happened in real life, I would be offended and completely freaked out. I just expressed attraction and then bam, mouth-rape. I felt extremely violated, even as a person who doesn't really care about gender. Immediately after discovering he's straight homosexual, starts making more sexual comments, particularly with Giselle. "You'd be surprised at the credit my tongue gets me." To his credit, when you subtly say that you're not interested, "You're brave," instead of "I think that makes you even better in my eyes," he backs off and it doesn't seem too awkward.
His romance, for lack of better words, lacks both romance, sincerity and integrity. It's apparently assumed that if two gay people flirt and find out that the other is gay, that's a green light to start sucking face, which is kind of the opposite of how real relationships work in real life.
Sera - I like her, but she's crude, enjoys torturing (figuratively) nobility, or people that she sees as "big people." Not exactly attractive. Kind of plain, veering on ugly. (That nose, yo.) I haven't romanced her (not a female), but I can only imagine that if I was, I'd just have to say that I too have a thing for my own sex and we would just suck face.
Anders - A rebel mage, impulsive, mass murderer, possessed. Varric ends up saying that he wound up insane in the end. Again, deviant. Expressing mild interest results in a make-out session without engaging in a romance.
TL;DR - Homosexuals in these games are depicted as sexually over-eager, and they are generally "not normal," ie. excessively crude, not serious, insane / possessed. Straight characters are far more well-adjusted or normal-ish, and require actual time / effort to get with, as opposed to simply finding out that they're of the same sex and interested.
