In all honesty, I don't find Bioware romance scenes very erotic, they have this awkwardness like whoever did it had their parents watching over their shoulder. Tthe best ones are usually the ones which let most of it to imagination.

However, I notice they are turning more and more... tame. Sure, you have a foursome on Dragon Age and some hot xeno gay sex in Mass Effect but the scenes are showing less and less with each passing game.

I expect Shepard to text dirty words to Legion on Mass Effect 3 has a romance option.
