If you were to die and someone found your dildo, why would you care? You'd be dead. I guess you'd just be worried about how that would damage the psyche of whoever found it. I highly doubt it would be nearly as painful to them to know you had a sex toy as it is to you to not have one.

I mean, I don't have a dildo. I need one really badly but I haven't gotten one because I can't ever get myself to spend money on one. But I mess around with stuff I find. I was home alone in my apartment for a week and my roommates came back a day earlier than I thought they were. To make it worse, I was not home when they came home and I left a few bananas, a butter knife, and a bottle of lube in the bathroom out in plain sight. Personally, I feel like that mix of objects is equally as embarrassing as a dildo if not more embarrassing because it isn't exactly common practice plus it leaves you to wonder what exactly I was doing with a kind of weird mix of crap. But you know what happened? Nothing. They teased me a little. I teased myself to own it. I cleaned everything up and our relationships weren't changed in the slightest. Okay, occasionally they mock me with fruit. But that's fine. I'll mock myself with fruit too.

You could say it would be different if your kids found it searching your room after you died, but it really wouldn't be. Unless they are so young that they wouldn't know what it was when they found it in which case it wouldn't matter, I'm pretty sure 99% of people know their parents have sexual needs even if they don't like thinking about it. There is nothing to be ashamed of.
