Well, I sort of told my dad I'm asexual, but I didn't go into it and about the whole I am asexual but I'm also gay, and that I'm a big ball of everything when it comes to romantic interests and gender. But if other people ask me, I'll be almost honest with them. Not about gender though, because if my dad found out he would kick me out of my house.
I'm bisexual so I don't feel as strong a need to come out. I don't tell people outright but I'm not exactly hiding it either. If/when I get into a serious relationship with a girl I won't hide it. Until then I'm comfortable being vague about my sexuality
