CMV: Everyone who watches erotica and feels stimulated is a voyeur

Lately I stumbled upon a few Subs where Voyeurism was discussed intensely. Some suggested to others to get therapy for feeling voyeuristic (don't know if this is a real word - non native speaker). I know this is a common phenomenon on Reddit threads and is suggested for nearly every problem someone has. But I am striving away from the original statement. In my opinion everyone who watches porn feels stimulation of voyeurism and thus is a voyeur. So as far as it's suggested lot of people should be in therapy for watching erotica. Am I generally wrong?
