I did once, but I never even finished that playthrough. It just felt.....wrong somehow. To me, male Shep's true love is his comrade in arms, Major Alenko. That's just the way it plays out for me.
Funny sidenote: Literally just yesterday, I started a new ME playthrough (to help kill time in the next month) and, as I was creating Shep, I thought "Maybe I'll have this one romance Steve and actually finish the game........Naaaaah, who am I kidding? There's no way that I won't be able to romance Kaidan!" Knowing from the very beginning that Shep and Kaidan will end up together totally makes me view their interactions in ME and ME2 in a very different light. And I love every second of it!
I think you know by now that we relate on a number of levels, this is sooo one of them
. Kaidan is my only canon romance, and worse, with modding ME1 to have him like me from there. I've done other romances, made other stories, but unlike my Dragon Age storylines, there's only one story I tell in ME in my head, and it involves Kaidan. Sad, I know.
Slightly OT, but I don't even remember this character being in the game. After hearing the name I had to look her up online but I still don't know who she is. That seems odd because even if I don't remember everybody's name, I'm pretty sure I remember every party member from every rpg I've ever played... except for her, apparently. I played through KOTOR many times, but for some reason she's not familiar to me even after seeing her face... I assume that she was in the Xbox version because I didn't see anything about her being removed from the game on the wiki... hm...
Juhani is hard to get and even harder to romance (you run a high chance of killing her while trying to recruit if I remember correctly), she's a Cathar (feline) Jedi Guardian, and while she's canonically lesbian, she's bi ingame due to bugs. And she's on every version (I've played Xbox and PC).
As for me, relating to OP, I wish Cullen was bi too. I don't care that he's race gated, but, yes, I wanted him to be bi. Maybe it was because there was money left, and I internally feel (my own prejudice of course), that it feels like another gay story apparently wasn't worth telling. Maybe because I'm afraid that the Iron Bull romance will end up really being a Friends with Benefits scenario and that isn't enough for me. And maybe I want a f*ing knight in shining armour for once. Maybe I want a templar (yes, specifically), who is interested in other men. Cullen had so little character in DAO anyway....
But now it doesn't matter. BioWare has made their choice. Locked it in. Any change at this point will get called fanservice and the LGBT fans might end up suffering as a result. (We did with Kaidan after all). Whatever happens, I just hope that the next hot templar is interested in men. And that, possibly, I can still flirt with Cullen and get turned down. He deserves to know how I feel after all.
