Edging accessories/toys

Hey all you strokers and schlickers, do you like to use accessories/toys while you edge? Which ones? What do you like about them?

I like my silicone ball stretcher (doesn’t really stretch but keep the sack taut and has a nice slight pressure) and I’ve recently found a rubber band I use that’s just a tiny bit smaller around than my glans (I’ll use one on my shaft for a short time as it slightly restricts blood flow). Also from time to time I’ll use an Aneros prostate massager that feels good too.
