I voted "yes". I'd want to know. I would probably know, or suspect, already.

BUT - I don't think I'd appreciate being suddenly confronted with the discussion, when I wasn't ready. I'd feel "on the spot" to discuss it immediately if my daughter just suddenly, out of the blue, said "I'm gay."

I'd like it better if she just hinted around a little bit, here and there, until the time came when we were both in the mood to discuss it. Then I could say "Yes, I know," and we could talk about it in a relaxed and leisurely manner. No pressure.

Like - my daughter has very slowly and comfortably let me know that she is sleeping with her boyfriend. Of course I strongly suspected it already. Since we eased slowly into the topic I never felt the need to express approval or disapproval, just acceptance and support. I would have felt awkward if she'd just said "Hey - Dan and I are having sex."
