What does that mean?
It sounds like a homo talking point.
It means what it says. How do these “sexperts” know so much about who is gay and who isn’t? Some God-given talent or just a need to feel like you can make wild assumptions? Yeah sure, sometimes it is obvious but to think you can size up an individual’s sexual preference(s) out of the blue then you’re probably giving yourself too much credit for having a well-rounded knowledge of human sexuality.
