Cortez thinks I'm gay, will it affect my chances to date women?
From reading through the Romance Mass Effect wiki page and LessPop_MoreFizz's succinct answer, it's clear that I can pursue either sex as romantic options.
However, from what I've read of other people's experiences in this area, once the crew figures out your sexual orientation, the opposite gender tends to keep their distance. For instance, if I'm playing a female Shepard and choose to pursue Traynor, Kaidan will pick up on this and take a few steps back, romantically-speaking.
So all of that leads to my question. Is it possible to have relationships of both a homosexual and heterosexual nature in the same playthrough? That is, can I hook up with a guy at some point and then, down the line, hook up with a female? Is it possible to have two such relationships at the same time even?
And where do the asari fit in the gay/straight spectrum? I understand they're generally considered an all female species. Does romanticizing Liara count as a gay, straight, or something else entirely?
