lesbian?

Any ladies who are lesbian? How did you come out to your friends and parents and well, anybody. I live in a Christian household and I love God and my church and I want to do the right thing but lately I've been talking to this girl and we kissed today... like... just...  it was so hot idk how I ever dated a guy. Like man... I don't even know how to explain it. I guess this means I'm either lesbian or bi. I don't know what to do..... please help?!
