I never found the DA2 Qunari face (because they all had the same face) to be attractive.
Too block-like and chiseled, no facial hair except for Salit, and I personally am not a fan of white hair on guys in fantasy settings.
Yeah I didn't find their faces attractive in DA2 but I liked the less human features to differentiate them from the "tall ashen skinned humans with horns" that are DAI's Qunari. Plus I didn't mind them strutting around Kirkwall in leather gear. 
What's the point in playing a fantasy game if you aren't going to bonk alien people? *sigh*
I like unconventionally handsome dudes in video games, and qunari are just that.
And when it comes to humans, I'd take Samson rather than Cullen.
I hope whatever gay companion we get in DA4, he is not going to look like something out of fashion magazine, or look too conventionally pretty.
Blonde beautiful chantry boys can ****** off. 
Because I'd still want to bonk someone human looking, just wearing a warrior's outfit or a mage's easy-lift robes.
I guess it depends on what you consider unconventionally handsome. The Poseidon guy I would consider conventionally attractive, just not the conventional age of sexual desirability. I don't need a male model, but I would rather someone conventionally attractive, whether that's a rugged dwarf or a more angular human, over a conventionally unattractive guy like IB. IMO. Personality and Qunari aside, I find IB's face very unattractive. His proportions don't match.
Personally, I'll take rugged over pretty.
I'm always going to prefer that the gay LIs be humans or dwarves, with qunari lower on the list, and elves at the bottom of the heap. (That said, I like IB and Fenris just fine, so it can work).
You mentioned "alien people." When it comes to literal aliens a la Mass Effect, I don't think I can do it. Personally, I really, really hope they don't give us a gay male alien romance in ME:A. Even if the alien is a new species. With the way they've depicted the male aliens thus far: Turians, and Drell, I don't think I could do the romance without it being weird. I can't do the carapace or bug eyes thing.
I would enjoy a gay male dwarf, as long as he's more of a Renn and less of an Oghren.
I am personally not attracted to alien romances, but I also don't want m/m options limited to aliens because it would feel like pushing the "less desirable" romance to gay players. Female aliens are attractive, mostly green-skinned women. Male aliens are not attractive and usually more of an animal-human hybrid rather than human-lite. I know others will disagree, this is just my stance on the aliens we've had so far in ME.
I mean, if there are six romances in MEA (and then I'll stop being off topic), straight guys get one human and one asari, straight women get one human and one drell/turian/new species, lesbians get an asari and a human, and gay guys get two aliens, that would not be fun. I doubt that will happen though.
