For me I became aware of same sex attraction at the age of 10 and knew I was a lesbian at the age of 12. I did however come out as bi a the age of 15 to test the waters and because I didn't fully accept my sexuality. A year later at 16 I came out as lesbian. I have now been out at my school for over a year.

In answering your question about wouldn't we always know our sexuality....well I don't think before the age of 10 people even start thinking about their sexuality. As children we just exist and don't dwell on gender and certainly not sexuality.
Then we are raised straight, by this I mean that generally parents do not raise their children thinking that they are going to be gay/lesbian/bi etc. It's not the case for all parents and upbringings, but it is for the majority of time.

I am really gald that you posted this as a Christian asking questions. It shows you are willing to talk and think about your faith which is how I believe all religous people should be like.

I am willing to answer anymore questions. I have alot to say about this kind of thing coming from the prespective of a lesbian Christian.
