Abuse screws up a boy's thinking in a lot of ways, and one is that he can become attached to the abuser. He may appreciate the way the abuser makes him feel special, he may like the sexual arousal, he may feel he is geninely loved, and so on.
I can tell you that when the abuser was chased away from me when I was 14, I positively grieved for him even though I had feared and disliked what he did to me. But I thought I was worthless by then, so just the fact that he was paying attention to me made me feel appreciated. When the abuse ended I felt abandoned and unwanted.
That's how messed up we can get, bro, and those feelings don't go away just because we get older. They are sometimes very difficult to give up. But the simple fact is that no one who really cares for a boy would use and manipulate him in this terrible way. Abusers are into abuse only for themselves, never for us.
Nobody living can ever stop me
As I go walking my freedom highway.
Nobody living can make me turn back:
This land was made for you and me. (Woody Guthrie)
