I'm pretty sure this might be an intrusive thought I have from ocd. Anyways, anytime I wash my hands, I make sure that every little bit of soap is off my hands. I even rinse my arms some because sometimes some may go on my wrist and i worry it could've made it's way up my arms. 

Then, when I shower, I also make sure literally every little bit of soap is off my body. I would go over everything. Even though I know and see the soap is off, I have this fear that somehow some might stay on my body that i might not see, or some might stay in my skin, or if some stays on my skin, it'll go in my mouth when I eat or something. And so, I take showers for like an hour because of this, but if i didn't worry so much, i could probably get it done in 15 minutes.

Should this really be something I should actually worry about? I told my therapist and she said a little soap would actually be ok to leave little bits of soap behind. And she said that a lot of hand soaps contain moisturizers actually.
