Pardon my ignorance. I don't spend much time on Facebook. It was more fun in the beginning, but reliving the clique scene wasn't my thing and I had to pull back. On two profiles of married adults, one a female acquaintance and the other a male friend who lives a ways away, they have "Interested in" filled in as "men and women." There is nothing in their family albums or other areas which indicate other people in their romantic or sexual spheres. They are also at the very least nominally religious, if not more so. Does this mean they are essentially proclaiming they are bisexual, or does this mean they just like men and women as people in an all encompassing, humane sort of way? And, yes, this is a real question.
It should mean that they would date men and women. It may not, but... Generally speaking, that's what that section is for. It depends on the age, though. If they're... generally 25 or under, take it with a grain of salt. Some people think of it as a joke. It's like how people pretend to be engaged or married or in civil partnerships (Teens, most of the time).
This. I can't tell you how many "FB Married" posts I've seen on my feed. On the sexuality question, it can probably be said that the answer is yes. At least what I'm getting from this. Off-Topic: I personally have the "interested in" on my profile hidden at the moment, but here in a few weeks or months I plan to change it to interested in men.
The feature's intended to be about sexual orientation yeah but people joke around so who knows~ mine is interested in guys
