Masturbating

I take care of a 4 year old boy. He went through a stage where he would always ask me to take my shirt off...take my jacket off, and he has an obsession with boobs. He also started trying to hump me...and many  times I saw him grabbing his crotch afterwards. I would tell him that is not ok and to get off of me. He hasn't tried this in over 6 months atleast but lately he has started humping his bed, the floor. And today he was "rough housing" with me. Pretending he was fighting me, then he started humping my back. I don't know how to handle it when it happens and neither do his parents. I feel very uncomfortable when he does this and I don't know whether or not I should punsih him or if I should ignore it?

He could be sexually abused. Its one of the symptoms.

I would not punish. I would have his parents talk to his pediatrician about it.

I would deff bring this up with his parents or a legal athority figure.
I finally found out not too long ago that my biological father sexually abused my cousin and I when were were around 2-3 years old.

My mother told me that me and my grandmother where wrestling on the floor and I stratled her and started humping her.
She asked me what I was doing, and my mom said I told my grandmother, "I keep you company."

That's when everyone found out that I was being sexually abused.

I would sit down with that boy and ask him in the best way you think he would understand, where he learned that behavior.
Maybe his father or another older male figure in his life is teaching him things he shouldn't be.

But yes, that behavior is one of the symptoms of a sexually abused child.
