My parents and uncle were talking about all the LGBTQ people they knew. I was so close to saying " i've been completely attracted to men all my life, no biggie" would this be a mistake, im almost sure there supportive, but would it be a mistake to blurt out something that major, would that cause a weird confusion, or would it be better to sit them down and do the whole, tears and hugging thing?
I struggled to decide when I want to let the real me out. I feel like I need to be comfortable after I test the waters. I feel like my friend is true and once I get a bit more confidence I will sometime do it (Strange that I keep telling to have confidence). Do it when you feel is appropriate. You will know. I knew now wasn't right for me.
Well you feel out the situation. In my opinion you should prepare for a serious conversation an kinda save the jokes for after; as long as everything's cool of course.
I would do it without anyone but your parents present as the first family members to hear it, and as a specific conversation. Since you live in San Francisco, they should be fully aware of what being gay means, so all they need to know is that you feel you ARE, so that they know what to expect as you grow older and want to start dating other boys.
