I understand that this is an M-rated game and, as such, it was meant to be played by adults. There are a number of characters that use more "colorful" language than other potential comrades. There are even other characters that are more likely to jump in the sack with ol' Shep than others.
My question is, if I wanted to choose my companions solely based on their chosen verbiage and sexual advances, which characters should I avoid to avert as much swearing and sexual deviance as possible?
Once again, I realize there is a dense amount of adult language and content in the game, and said content cannot be avoided completely. I just want to know whom to avoid to minimize the likelihood of these occurrences.
Edit: Total question rewrite!
