Forum:Will gay romance options hurt canon?

I was reading a bit on some other sites and people seem to be mad that some characters are going to suddenly turn gay in the 3rd game, However i disagree with this, garrus for example never says "Shepard i'm straight". So you can't imply their 'turning' gay in part 3 they could have been gay all along, i mean in mass effect 2 us male shepards never see garrus getting it on with a woman, and in ME3 female/straight shepards wont she garrus getting it on with a guy either, so does it really ruin the canon? i dunno what are your guys' thoughts? (it's not confirmed garrus will be a same sex romance option, i'm just using him as an example.
