Pillow humping and cumming?

I know many women do this or have done this. It is not just me. Obviously more then 100 women do this due to the fact its on google.

I am 21. And i dont know when this pillow humping started but its the only thing that can get me off. Seriously.

Sex, oral, dildos, lubes, vibraters, rabbits the lot it doesnt get me off in the slightest.

What i want to know is how the HELL do i stop doing this and actually get turned on by sex or other forms of stimulation. I am begging for help now. I thought id grow out of it but i havent and didnt. So someone that used to do this tell me what helped you stop!
