Is it normal that i can't control my thoughts?
Here's a few common situations for me:
I go to the toilet and take a dump and out of nowhere I see an image in my head about taking my shit and putting it in my mouth.
Whenever someone comes to borrow something from me I think about saying "Sure, but only if you suck my dick".
Whenever I see some girl on the street I think about tackling her and when she's down on the ground I fuck her in public.
I don't act upon any of these thoughts, but they just seem to spring up randomly in the weirdest times and it's hard to shake them away. Any advice on how to better block out the nasty information?
