Intrusive thoughts vs sexual attraction

How can you tell the difference? I have been questioning this for a year now. And everytime they tell me the difference they say things like ‘’ intrusive thoughts are not something you enjoy and sexual attraction is something you enjoy or desire ‘’. Which before, i understood it. And now, Idk if im having intrusive thoughts or genuine desire. Idk what sexual attraction is and i always mistaken it with other attractions. But yet Idk if the thought im having are intrusive or not . Bc anytime when these thoughts come in, i would be very disgusted and uncomfortable and theres that weird voice that keeps convincing me that i enjoy these thoughts. But Idk anymore. What do you guys think?
