I don't think the real problem is Bree having more male options, because if it were a separate game, no one would have a problem with that. What I think is that, inconsistently, we still see Mike as the protagonist, even when playing from Bree's perspective, which is why it can feel strange. Most of the male characters are "okay" (a nerdy metalhead, your roommate's ex, Jonn Wick, and Master Roshi, the guy from the electronics store), except for those who can be considered antagonists or villains from Mike's point of view (e.g., Angela, Dwayne, Danny). There, I could perhaps understand some of the discomfort some players may have, since, unless they have a path to "make them better people" (I don't know, I haven't played from Bree's point of view yet), it would be weird to date them. Especially given what they've done to other characters, like Cassidy, Cherrie, Aletta, Minami, Mike, and Lexi.
I know Mike is not a saint, and that girls like Kylie, Morgan, Cassidy, and Alexis are not either, but the damage they can cause or did can be fixed or avoided in one way or another, hence also another reason why they may not have the same stigma as some of Bree's male cast (except for the pair of sisters, they need therapy and only one manages to get it)
