GM-08 - In his book By silence betrayed: sexual abuse of children in America, John Crewdson includes a woman's recollections of her consensual sexual relationship with a handsome neighbor, Clay, at age seven.

She recalls that she really loved Clay romantically, like a woman would love a man. She found it exciting to have him so near, and found it beautiful to be embraced and touched by him. Although having orgasms was not the most important aspect, she also liked the sexual part. 
In general, she already liked the male body at that young age.
