Apart from just putting elasticated hairbands round my cock and balls the only thing I've really done is use a TENS massager which was quite good sticking the pads on the balls and round the ass. Some of the high settings gave a bit of a kick but what else can anyone recommend either mechanical or electrical for more intense stimulation ?

sonic type electric toothbrush. Remove brushes and it feels great

Damn that looks hot. I'd love to try one with the urethral amplifier.

Certainly looks interesting although quite expensive and some of it looks rather homemade. The testicle electrodes I could definitely look into. Love to use them with a fellow bi perve.

I use metal cock rings with my balls pushed through and leather strap too

But that doesn't do anything though ?

I don't think there is anything homemade. I've been to their factory and shop in Las Vegas to purchase various items. It's all pretty high quality stuff in my opinion.
