Some of this is just my personal opinion which may differ from others, so keep experimenting to find what is right for you.
When we stim we are fooling the innate, subconscious areas of our brain into believing we are having sex. Orgasm is an involuntary, psychosomatic reaction to the electro-stimulation applied to the relevant sexual nerves.

Perhaps the most important is the DORSAL NERVE. This runs along the top of the penis to serve the cock head. Best to stim this one over or just below the glans. You can use a TENS pad, a Conductive Rubber loop or a metal ring. Advanced stimmers might try a urethral insertable.
Next in importance are the PERINEAL NERVES, accessed via the balls. The perineal nerves offer a deeper, more subliminal stimulation that intensifies orgasm. You can stim these using a large CR loop, a TENS pad or a suitable metal ring. A CR loop is best applied behind the ball sack up to the pubic mound at the back of the penis (upper side). A pad can be positioned as per the image below. Otherwise a pad can be positioned on your perineum.
- Ideally you want to be stimming the DORSAL NERVE and the PERINEAL NERVES on the same channel, i.e. 2 electrodes working together - MMMmmmmm, yummy
- Some like to stim the SCROTAL NERVES, lower in the ball sack. Personally I find these a bit too sensitive, sharp and painful but hey, whatever floats your boat
- For anal play you need a decent anal insertable and plenty of lube to get it in. You are aiming to stimulate the INFERIOR ANAL NERVE and the DEEP PERINEAL NERVE which in turn will stimulate your PROSTATE. Importantly you DO NOT want to stim the SCIATIC or SPINAL NERVES located in the upper reaches of the anal canal. - You will know if you hit these because it hurts like hell
*** INSULATING TRODES TO AVOID DOUBLE-STIMMING THE DORSAL NERVE...
If you are using a pad at the base of your cock it should be placed on the underside. If using a CR loop at the penis base you should insulate the TOP HALF of your loop with insulating tape. Otherwise you have TWO separate electrodes BOTH stimming the Dorsal nerve which runs along the top of your penis - causing interference, harshness and cross-chatter.
Same goes if using a ball loop - ALWAYS INSULATE THE TOP HALF.
