Kegel muscles are good for using Aneros, and they're supposed to also improve ejaculation distance. Particularly *reverse* kegel exercises, because cumming is like forcing liquid out, not like contracting muscles to keep it.
There's a new kind of stretchable cock rings available. It has what looks like elephant ears. It made no sense for me until I saw the video. Those ears make it trivial to quickly put it on and take off. You stretch the ears and it stretches the cock ring.
So what I'm planning to do is: buy one of those, keep it in my pocket, and *every single time* I pee instantly put it on and work out my kegels. If the ring is tight enough, it stops the urine flow, and you push with the muscles to force it out.
Pro tip: you can achieve almost the same effect by pinching your penis with 2 fingers. Lol
