An eighteen year old writes about being raped as a child, as well as her consensual relationship with a nineteen year old when she was twelve: 

“I was in complete agreement with all that went on in that relationship, and I was not at all manipulated.

As of right now, I am an 18 year old girl, with a past with sexual abuse. When I was a child, I was raped and molested by the adults that I felt I could trust the most on three different occasions, by three different adults. This has given me an intense distrust of people, in general, as the child molesters consisted of both men and women.
[...]

Being a girl that refuses to define her sexuality, I firmly believe that love is never wrong. If coercion, manipulation, and force are completely absent in your interaction with children, there is absolutely nothing wrong. 
[...]

As a girl, I was always attracted to older men. The oldest I had ever dated was seven years older than me, and I was only 12 years old. And technically — that’s pedophilia. I was in complete agreement with all that went on in that relationship, and I was not at all manipulated. 

I can attest that children are indeed sexual creatures — but I think it really all depends upon the child. I myself, for instance, began masturbating at the age of 4 years old. But I don’t believe that I was ready for a romantic relationship with anyone until I was about 11 years old. Even now, as a technical adult in the United States, I am romantically involved with a man 4 years my senior. And while that isn’t a big deal now that I’m of age, it was much more so when it was initiated!"
