Can you really just perform a medical procedure like that without any payment involved? What happens if something goes wrong?
11AnonymousNov 13, 2026 23:36
These days the only guys getting that done are ex-cons fresh out of prison — it looks grotesque too.
12AnonymousNov 13, 2026 23:38
What's even the point of putting silicone in there?
13AnonymousNov 13, 2026 23:40
Even looking like that, a good-looking guy's still a good-looking guy.
14AnonymousNov 13, 2026 23:40
Not many guys out there have had their junk handled by both a daughter and her dad.
16AnonymousNov 13, 2026 23:42
Gross, don't just drop a thread title like that on me — that's basically harassment.
18AnonymousNov 13, 2026 23:43
Gave hentai writers some good material there — a former idol with silicone implants.
Depends on the timing I guess, but hey, it's his body, his choice.
20AnonymousNov 13, 2026 23:44
So it's silicone, huh — not the usual toothbrush-handle "bullet."
21AnonymousNov 13, 2026 23:44
Worried it'd feel too stiff when things get going, but also worried it'd look like some kind of weird growth when soft — gross either way.
26AnonymousNov 13, 2026 23:46
What does it even end up looking like?
Can't picture it.
27AnonymousNov 13, 2026 23:46
The fact that he's still got fans sticking around after this — that's wild.
28AnonymousNov 13, 2026 23:47
"Something like a toothbrush handle, polished shiny by rubbing it against a wall," "then you make a hole with something sharp, right there in your room, in your own private parts. And push it in hard…"
43AnonymousNov 13, 2026 23:56
Just file a toothbrush handle down round and shove it in.
68AnonymousNov 14, 2026 00:12
Truth is he probably had a toothbrush handle filed round and implanted back in prison, right?
71AnonymousNov 14, 2026 00:14
Re: #68
This part's a mystery to me — how do you even insert it with no tools at all?
It's embedded inside, not just slipped between the skin and the shaft, right?
74AnonymousNov 14, 2026 00:18
This is it

The strange, winding path a life can take to end up here

What a rollercoaster of a life.

Has his little brother cut ties with him?
77AnonymousNov 14, 2026 00:21
Re: #76
They're actually really close.
85AnonymousNov 14, 2026 00:26
So basically he had little bumps added, like on a dildo?
86AnonymousNov 14, 2026 00:28
Re: #85
Simply put, it's the same idea as breast implants.

Background and Key Points of This Discussion

Inserting silicone into the genitals is a procedure known in some circles as a way to alter firmness or girth, and as repeatedly comes up in the thread with talk of “filing down a toothbrush handle and inserting it,” it has historically been done informally rather than as an official medical procedure. What made Sei Tanaka’s confession stand out this time is that the person who performed it was a private individual — his ex-girlfriend’s father — with no clarity on whether he held any medical qualifications or how safe the procedure actually was. The thread’s reaction was also shaped by the backdrop that Tanaka was previously arrested in a drug case and left KAT-TUN, remaining a recurring topic of discussion even after stepping away from entertainment. The thread split between shock at “did he really need to confess this” and pure curiosity about how the procedure itself works, with the latter driving many of the conversation threads questioning its effect on sex. That said, unverified claims — such as lists of unconfirmed past relationships — have not been included in this article.
