my favorite type of dehumanized male is like a mindless naked android...so obedient that is it programmed!  PRE-obedient but still passable as a normal muscle male when clothed and at the gym or completing a task. just no need for personality or independent thinking...

...  your balls produce less sperm when they are hot... that is why they will hang lower as if they are panting and trying to cool off.   if you put your balls into a mug of ice water several times a day you will see your sperm wads get much bigger AND you refill faster after just a few days of chilling.

i will train you now so you can practice.   and why the hole has to be flushed clean and empty!!   as cock slides into muscle hole, instead of just staying relaxed,       think about PUSHING OUT gently with the hole muscles   as the cock slides out,             try PINCHING  DOWN  (as if are stopping turd flow).     this muscle activity requires true submissive obedience.   it also develops  more sensation in the love hole.

boys: Please Play Plenty!

i have owned slaves in past who i had the chance to actually develop their ass muscles into toned into stroking machines ... once the muscles hit their limit, they will fatigue and sometimes ( or often) spasm like any other muscle.  that is what makes your balls spasm out sperm.   the ass hole muscles can also spasm at the same time of balls spraying, the pulses are in synch.   however, u can achieve gentle long lasting spasming in your hole muscles with out spraying sperm... the hole does NOT clamp down extra hard with full clench with each sperm pulse... the spasms can ripple around any transverse or lateral random direction... and last a LOT longer since you are not depleting your current sperm load... AND you do not get the primal guilt flood and energy drain like real males experience when they release their sperm.   these spasms feel intoxicating for the bottom and most males like the feel of it on their shafts...  chastity can really make this happen faster for the bottom-in-training (especially straight male slaves); dildo and plug play can help some guys get there faster.... but the best method is steady regular fucking by an owner or brother slave or lower ranking slave u have control over...  make him refill his balls faster by immersing his (or any guy's) testicles (and cock for torture) in ICE WATER as often as u remember.... more to cum...
