I too have recently been doing kegels. After a couple of weeks I have found it to be suprisingly effective. Given that there are so many bullshit 'miracle' pills, exercises, pumps, silicone freak show operations and the like to either grow, thicken or the like to a cock it's nice to discover something that genuinely works.
Not too long ago while being JO'd by a dude I sometimes mess around with I was given my first piece of evidence that kegels worked: usually when i shoot while quite a bit ejaculates out the force is not so impressive- just one or two spurts then just oozing. This time before I even shot a large amount of fluid shot straight out of my cock and traveled pretty far. I didn't feel a thing. Not a 'contraction' that tells you you're shooting something of your cock or a squeezing sensation that says your cockhead is shooting. This came from deep inside and was powerful enough to send a lot of jizz from my prostate a couple feet across the bed! To add to that when I did shoot it was a huge amount and shot pretty far.
