Make relationship status a required profile field
But let the user choose whether they want to show or hide it on their profile, just like age.
That makes no sense...personally a married man is hotter ;) coming from a bi married man whose wife knows and participates from time to time. Even she agrees a married man sneaking around to sleep with men is just hot.
People could still lie, just like they do with age
What's the point of that?!
