In short

Customers reported both prostate orgasms and unsuccessful attempts; one report included prolonged inability to urinate.

Mr. Okada repeatedly said he knew no dependable shortcut and considered mental state alongside physical stimulation.

Current listings include related chips, but the diary identifies no universally suitable model.

If you see blood in your urine, even a small amount or for the first time, do not wait and see. See a urologist right away.

If you suddenly cannot urinate, or the device cannot be removed, do not try to fix it yourself. Go to a medical facility, including emergency care, immediately.

What happens: reaching a prostate orgasm

The OK Prostate Chip is a small urethral device designed to press on the prostate from inside the urine passage. These entries discuss dry orgasm (orgasm without ejaculation), which customers hoped this prostate stimulation would help them reach. Other passages consider outside pressure and vibration, while Mr. Okada repeatedly acknowledges that physical stimulation alone does not explain everyone's response. Customers' descriptions differ, and the reports include unsuccessful attempts and adverse symptoms.

Linked chips carried bladder risks alongside the maker's dry orgasm claims

An entry published in January 2018 announced linked and long chip types, then explained concerns about the linked design. The version discussed had a 0-2 mm gap between chips and an overall length of 5 cm or more. Mr. Okada warned that its length made unintended movement into the bladder easier.

The diary describes the inner urinary sphincter (a closing muscle) as helping prevent semen from entering the bladder. Mr. Okada warned that a chip crossing this muscle could allow semen to flow into the bladder during ejaculation. He explicitly discouraged beginners from choosing the linked design discussed there.

A dry orgasm report described progress after a year

In an entry published in March 2019, a customer requested another repair after a retrieval thread detached from a resin chip. Mr. Okada proposed a replacement because further repairs would add material to an already repaired product. He offered the replacement for the repair charge, while explaining that its shape would differ.

The customer accepted and reported recently reaching dry orgasm with the chip alone after a year of use. The diary does not record whether the replacement was subsequently delivered or how it felt. Mr. Okada presented the customer's experience as encouragement for people whose hoped-for response had not appeared quickly.

An insertion problem complicated one customer's pursuit of a prostate orgasm

In an entry published in June 2019, a customer wanted a glass vibrating chip's 10 mm motor replaced with an 8 mm motor. They also requested a ceramic chip because they could not insert their existing long glass model. Mr. Okada said only the electronic controller could be retained if both components changed.

He refused returns of chips and motors, including unused ones, but offered to transfer the controller without charge. Ceramic vibrating chips were awaiting release; the customer acknowledged this, but the diary does not record a completed replacement. Mr. Okada suggested considering friction and angle as explanations for the difficulty, although this was his assessment of the customer's report.

A separate pressure frame entered the maker's dry orgasm discussion

In an entry published in April 2020, Mr. Okada presented a second-version external pressure frame associated with his own dry orgasm experiences. He described the redesign as easier to handle and more visually appealing than the earlier covered frame.

The simple version cost ¥5,000 (about $32 at ¥156 = $1, rate as of 2026-09-04) excluding tax, as published in April 2020. A tip-mounted motor was included, and Mr. Okada claimed the frame could also produce the desired response without vibration. He specified separate purchases for the controller and pulling cord.

The dry orgasm manual offered suggestions without guaranteeing results

An entry published in July 2021 reproduced a manual that explicitly denied any guarantee of effects. For absent sensation, its suggestions concerned larger shapes, stronger stimulation, body position, vibration, and additional sexual stimulation.

It also claimed that ejaculation need not end the experience while a chip remained in place. The diary does not record outcomes for readers following those suggestions. The manual also advised stopping use if unfamiliar discomfort developed.

One dry orgasm report included hours of inability to urinate

In an entry published in May 2022, a United States customer reported symptoms involving an S-size chip nicknamed Zoro. They wanted to know whether similar problems had been reported. They described continuing orgasms for 30 minutes to 1 hour after the chip was removed.

They also reported inability to urinate lasting 3-4 hours, or approximately 10 hours in longer episodes. Mr. Okada said he had not experienced this himself and asked whether the customer felt an urge but could not pass urine. He sought reports of similar problems; the diary does not record a diagnosis or medical follow-up.

The maker's answer to reaching a prostate orgasm

Mr. Okada's replies emphasize individual response, while his design experiments do not establish a dependable route to orgasm.

Quiet pressure shaped Mr. Okada's early dry orgasm theory

In an entry published in January 2018, Mr. Okada described tests of different gaps between linked chips. He found a 10 mm gap less satisfying, while approximately 3 mm restored some sensation around the closing muscle. Touching chips could bend at their meeting point, which he believed reduced strain.

He announced cancellation of a long-version release in favor of this linked arrangement. His personal definition of dry orgasm centered on spontaneous rhythmic activity arising from quiet pressure, without genital contact or vibration. Mr. Okada therefore favored reducing direct muscle stimulation in the linked design he was developing.

Feeling close did not produce a dependable dry orgasm shortcut

In an entry published in February 2019, a screw-chip customer asked why they repeatedly felt close to orgasm without reaching it. They wanted a practical tip that would bridge that gap. Mr. Okada replied that he did not think there was such a trick.

The diary does not record whether this customer later reached orgasm. Mr. Okada suggested serious attention to one's body and state of mind as the most promising direction.

Longer dry orgasm sessions raised concerns about resin discomfort

In an entry published in February 2020, a customer asked about extended use while pursuing dry orgasm. Mr. Okada described his own resin-chip tests, reporting a sticking sensation after approximately 10 hours without vibration.

His reply also favored daily condition checks for ceramic and glass chips. He acknowledged reports of longer resin use from customers, but those reports differed from his own experience. Mr. Okada did not recommend 24-hour continuous resin use.

The maker associated prostate orgasm with spontaneous muscle activity

In an entry published in September 2021, a customer asked whether deliberate PC muscle activity was enough to reach orgasm. They also asked whether outside pressure helped or interfered with that goal. Mr. Okada regarded pressure around the perineum (the area discussed as an external pressure point) as possible support for prostate sensations.

The entry records no subsequent orgasm result for this customer. Mr. Okada favored spontaneous muscle activity, while emphasizing that mood and physical condition could change the response.

If you suddenly cannot urinate, or the device cannot be removed, do not try to fix it yourself. Go to a medical facility, including emergency care, immediately.

Common worries about reaching a prostate orgasm

The replies leave important questions unresolved, including individual response, exact chip position, and why some customers cannot progress.

"Does no prostate orgasm mean the chip is misplaced?"

In an entry published in February 2019, a customer asked whether the chip had reached its intended position because the expected orgasm had not occurred. They also raised concerns about possible movement into the bladder.

Mr. Okada said the differences in urinary anatomy described by customers made suitable advice difficult. The diary does not record confirmation of this customer's chip position. Mr. Okada asked readers with comparable experiences to share their observations.

"Should a chip be forced when pursuing a prostate orgasm?"

In an entry published in February 2020, a customer asked whether to force a chip that would not advance. Mr. Okada suspected insufficient moisture, while acknowledging that other individual factors could be involved.

He associated forced movement against dry tissue with bleeding. The diary does not record how that customer's difficulty was resolved. Mr. Okada explicitly discouraged forcing the device in those circumstances.

https://ok-lab.hatenablog.com/entry/2020/02/29/155031

"Why does a prostate orgasm seem absent after initial sensations?"

In an entry published in May 2022, a customer using an M-size semi-long resin chip asked whether the initial sensation would continue. Mr. Okada said some people reported sensations during passage but little afterward.

His explanation associated the semi-long shape with muscle contact, although he did not confirm this customer's actual position. The entry records no later result for that customer. Mr. Okada suggested considering both physical stimulation and mental state when interpreting the response.
