Dads to LGBTQ children, did you knew about their orientation/identity before they came out to you? How did you handle it?

As you can probably guess by checking my profile, I'm gay. I've never been in a relationship nor have had sex before, I'm also not out to my family (just friends and some other people), so I wonder if my parents may have already guessed it and know about it or they are completely oblivious to that part of me.

Still, even if they might know by now I'm not going to come out to them until I have a place where I can go to Incase I get disowned or something.
