For context, I am 19F, and my roommates are all 19-20F. My roommates are also straight.

I feel like I should have told them and let them make a decision based on that information, as I understand why that could potentially make a straight person uncomfortable. But I didn't because it's a very awkward subject to bring up, and I really hate telling people about it. I'm not openly bisexual, so I don't really have to worry about someone telling them, but I do worry about them finding out somehow. I feel like I lied to them and withheld information that could have had a significant impact on their choice to room with me. They seem to be at least ok with gay people in general, as in they don't care what adults do in their private time, but their feelings about living with someone who is attracted to women could be different.
