The only ones I had hitting on me were Tali and Liara, and one of them is already supposed to be our canon romance with the writers practically telling us via auto-dialogue that we love Liara.
Jack hits on you automatically, Miranda does as well if you don't take the middle option out (I was trying to be nice. So much for that).
That's what happens when you keep picking the top right button lol 
Not even! I picked neutral choices. My guy was a paragade and I still got goddamn ninja'd. It seems oddly the only way to get her to backoff is if you're romancing Liara. O_o
I am not saying that Mass Effect is a perfect example, I'm saying that the scenario with a MaleShep and Traynor is something I'd like to see in DA rather than all the LI's bending over for the Inquisitor.
Shepard may get more offers, but he can't change people's sexual preferences.
And if you say "well neither does Hawke, their sexual preferences just change based on the gender that Hawke is" I'm gonna playthorugh DA:O just so I can kill Alistair.
When did Hawke change anyone's sexual preferences. Please tell me I'd dying to hear this. Or are you assuming everyone's straight until they scream at the top of their lungs that they're not? And no saying you want a pretty girl is not declaring straightness it's simply saying you're attracted to women.
Also you can easily have Lis not bending over for the protag with all bi LIs. It's as simple as having them react to your actions something I see many pro playersexual Lis in this thread (including myself) asking for! I'd rather an LI be equally willing to romance my male and female but go ah hell no to my mage who sacrificed innocent elves for 10 damn health points (if they themselves are a "good" companion) than ignore that because she has ovaries and since my male can't romance him that's enough of a restriction. I rather restrictions go towards the main plot maybe some exclusive things for each race and class. I'd get far more mileage out of that then from an LI.
