OK, so edging with cock warming is having a dildo in your pussy and just holding it in there without manipulating it. I'm assuming you can feel it in there as you move around and it increases the edging stimulation.

So, what I like to do is slip on a masturbation sleeve. It took me some trial and error to find just the right one but now I have one that is a very flexible and a pretty thin silicone sleeve. It has nice bumpies on the inside and it is a closed end sleeve. I am able to wear it inside my underwear and pants and go about my day and no one knows I have it on. It's not noticeable unless I get a really strong hard on and most of the time I'm just semi-hard. I usually wear a sweat shirt and that covers the front of my pants very well.

Its just so freaky to be walking around in a store or anywhere really, like maybe pumping gas, and just slipping my hand into my pants and giving myself a few secret strokes. I do look out for other people and cameras and stuff.

When i first slip it on I put a few drops of lube but as I edge my dripping cock precum supplies more than enough lubrication to keep everything nice and slippery. I even sleep with it on and waking up this way is awesome. I wear spandex girls boy shorts and they keep it nice and secure.

so, would this be considered the male equivalent of a cock warmer?

Maybe a pussy warmer?
