If you like to challenge yourself while masturbating, this technique may be a good test of control and concentration.
Get hard , but just enough to have a firm erection; stroke until your cock stays firm on its own for about a minute without stroking.
Grab cock, stroke it once and stop, grab it at the base and make it 'dance' twice. Then stroke yourself twice, grab it at the base, and make it dance four times, etc.
Each 'progression' you 'dance' your dick twice as many times as you stroke it. The more strokes you do, the more 'dances' of your dick you have to do, so as the session progresses, the interval between strokes increases, but when you recommence stroking, you'll have 'earned' more strokes.
If you're into 'being your own cocktease' like I am, this is a wickedly simple way to drive yourself absolutely cockcrazy to cum. Porn is optional; see how far you get without it first, because the porn may make you lose concentration, which is very difficult (for me, anyway) as the jack session progresses. This is a handy (no pun intended) technique to have available when you might not have access to porn. It's visually stimulating to watch yourself in a mirror when using this j.o. technique; don't be surprised if you see some pretty desperate looking 'cum faces' as you get into the longer 'dick dances'. As I mentioned, this requires a lot of concentration and self-control.
The best part is, of course, when you reach 'the point of no return'; then you just pound your piece with total abandon. Crossing the boundary from control , bult up over so long, to out of control is 'super freaaakaaaky'. I have added another challenge to this technique that puts a nice 'twist' on the finish strokes; I keep away from the porn till I start losing my nut, and than look at it when I'm in orgasm. You'll be surprised at how much more of a nut you shoot off because of the 'porn denial'.
Cockplay for SOLOSEXUALS like me is very important; I'm always trying new challenges. Seeing how far I can go, and then going beyond 'personal best' records really gets me off, for some reason. I guess guys just like numbers.
So there's the 'challenge jack' method I use sometimes; it works best for me after a couple of 'rest days' from masturbation. That's a big part of the challenge sometimes; I get really horny, but gotta stay off my dick for a couple of days, and I can really get my 'old solidier' to 'pop tall' and perform. Hope someone will try this and share their results. Happy wankin to all...DoctorJack
