Hi Happily_Saved,
It looks like you have gotten a lot of good advice. I agree that if for whatever reason, you don't feel comfortable telling your parents, you shouldn't feel pressured to.
I too was sexually abused when I was young, by a relative. I ended up telling one of my aunts but I could never tell my dad because of fear that he would do something to the abuser out of anger. That is my own reason. However, it is healthy to talk to someone about it. It sounds like you are a Christian...what about a pastor or someone in the church whom you can trust? There are great healing ministries for people who have been through such awful hurts like this.
You have taken a positive step to bring this out in the open!
