As long as I'm not thinking I'm having a bro moment with one of my squad mates, and he tries to kiss me. I'm good. Man, i couldn't talk to the guy that flew the small ship in 3 cause I was afraid of choosing the wrong dialog option lmfao
They actually did a good job with him. He's cool.
Kaidan, the guy that was not gay but magically became gay, is the bro who makes a pass at you out of thin air and does this because he thinks you're into him too. So not only is he now gay but your behavior toward him gave him the impression you were gay for him. Even though he was not a romance option for males prior to ME3 and nothing you do can be contrived as flirtatious toward him. Just out of the blue let's make this bromance into a romance.
Eck.. gay Kaidan. At least if you romance anyone other than Tali you would avoid it. Of course, knowing when it comes up you can just stay clear of it until after you reestablish Tali romance
Cortez gets a thumbs up. You can be bros with him just fine with no awkwardness. You will actually have to make actual choices before he would come on to you like Kaidan does.
