I have discovered magical things about my body. I didn't realize how much I've been neglecting my balls while I edge or masturbate. Usually I slide my hands over my stomach and chest, sometimes squeezing myself in those places as well, but I'd never really touch my balls. I'm not sure why, especially since I like my balls sucked.
I also really like humping my bed; often also rubbing myself left and right against it. I thought it was just stimulating the underside of my glans and shaft, but recently I was really feeling it out while doing it and realized I like that my balls are rubbed left and right as I do that, too. So that got me thinking...
Today, while edging, I grabbed the base of my balls/scrotum with one hand and tried jerking it similarly to what I was doing with my other hand on my shaft. It felt pretty good! I also realized I could grab the part of my shaft that's not visible from outside of my body and switch back and forth from stroking/jerking my balls to stroking that.
It feels really nice to softly massage my balls all over while edging/masturbating, so I'll definitely be doing it a lot more!
