I joined a dating site and had a chat back with this lady (I'm bi) Then she sent me these questions:
Why would she want to know about my childhood? Does that sound like a red flag?

She may just be making conversation or she could be trying to get information about you. I've never used a dating site but this would raise a red flag for me especially if it was someone I hadn't known long. But I'm also probably more private than the average person. Personally I would keep it very general.
