Best practices for semen extraction or sample collection?

Wasn't there a movie or a TV series where the men were subject to ongoing semen extraction by having a catheter insert in their penis and into their testes. They were in a state of stupor while this was happening. Probably not orgasmic!

@mike45 , you don’t have to be my hubby. I also did it to another Zity member here.

Wow! Can I sign up too ! ;-)

@Miss_Sarah oh my... You are awesome!

I sometimes stick the large end of an aluminum baseball bat in my ass while standing. I lean back, bend my knees a little bit to get deeper penetration, then move my hips forward, which pushes the bat against my prostate, then stand up. this causes the cum to gush out of my penis. I can do this several times to get a handful of cum. I dont save it for the doctor though. I just lick it off my hand and swallow it!!

Medical electro through the rectum is apparently very painful, requiring anesthesia if patient can feel pain. See the last video for how it's done

Several e-stim videos of ejaculation see the xhamster and pornhub videos. I have no experience. I wouldn't do it myself unless tutored by someone experienced.

As part of my Medical Fetish play I have recently tried Hands free masturbation toys , I love the feeling of being " milked " whilst reclined, fully Naked of course - in a sort if Gyno exam position . It feels exciting and Clinical to slip the lubricated device over my Penis completely and then the anticipation before it is switched on gently rotating or thrusting, it can stimulate me for ages until I eventually explode !.

Mary Palm and her 5 sisters! Or J i l l !

My play doctor after pluriennal experience on my body maximize the sample volume with a commistion if penile teasing and balls busting.

She ties me on a gyno chair with legs spread then dilate my rectum and place a metal dilator. In position after my external sphincter. She ties my scrotum pulling the glands to distend my seminal vescicles. Having that gives a feeling like testicles were to be separate from the rest of the body... Keeping retraced the penis she starts a continous teasing of the glans kept lubricated by my own precum. She is so expert to dismiss the stimulation when I am near the ejaculation. She edges me for hours. She knows exactly where stimulation shall not be administered like the frenulum or prepuce. My glans get sore and extremely sensitive having the urge to ejaculate but I never climax without her consent (few times it happened I was harsly punished), finally places me in four legs position with a glass dish under the penis. She keeps firmly my ball sack squeeze my testicles while deeply retracting my pepuce with the other hand. I almost immediately start ejaculating with several huge spurts of semen she enhance squeezing my oenis and glans. It is always a massive release and I feel exhausted after that.

There are several techniques to maximise the sperm extraction but I think that two of them are a must, I'm talking about forced chastity or abstinence before the exam for at least one week and cum control/edging during the exam that enhance the sperm volume and the urge to ejaculate. Obviously this two techniques involves a huge humiliation for the patient that must submit to the Doctor's orders.
