Once per day, when peeing, do it differently. 1. Release the stream during the in-breath. 2. Stop and hold the stream on the outbreath. 3. If not yet bored or tired go back to 1. Else - finish peeing normally. That's it.
And note that for most people, a week to few weeks of the exercise give stronger orgasms and ability to delay the ejaculation.
I usually got bored halfway and after 3-6 breaths finished peeing normally. It was also because I've noticed that the exercise made it very hard to push out the last of urine from the bladder. Now I know it's also very unhealthy not to empty all the way.
