Um, simply & discretely move it to elsewhere in the room that's not in line-of-sight perhaps? Or put on your Big-Girl pants and delicately broach said subject matter verbally with him?

Just don’t be a dick about it

Be a double dick about it

How hard is it for you to put it in a drawer? Or the trash?

I know it's hard but try to square things up..

Grow up. Grab it with a hand towel, put in a drawer, then toss the towel in the hamper.

Poke him in both eyes with it.

That’s not OCD, it’s just the right thing to do.

Just quietly put it in the trash and never speak of this again

I’m going to have to agree with everyone else — there’s no reason both of you need to be embarrassed. Put it in a box under the bed. Stick it in the back of his underwear drawer. Hell, just throw the damn thing away. Anything other than telling him.

At least she didn't leave it in the toilet.

"hey dad, what's that?"

I don't understand why you have to tell him. just throw it away
