For what i recall, from being chronically online:

They go in around your lil guy and release the shaft from everything around it and shift it forwards. It gives you more visibility of what exists but does not actually make anything bigger. Idk about adding anything, because i did not look into it further.

Rumor is that's what happened to Elon's dick. Botched enlargement surgery.

It's my understanding that it's more of a last case scenario kind of thing, like, most guys don't want to have surgery on their penis and it can also have complications too.

The real question is, why isn't this covered by Medicaid?!

I would say it's probably not worth it just because you will most likely have sensory loss and erectile dysfunction which for most would be worse than the problem its self. Theres more risks as well, but those alone sound like a nope from me.

Apparently it's only girth they can modify. Not length.

It exists, but the complications are prohibitive for someone that isn't hit with disability level malformation. Plus, there's a limit to what it can do

/uj some of us are happy with what we got. Also there is a things as too big. I don't want to hurt my partner.

/rj you sure you want 3 Steven Millers on your crotch?

The surgery went a success but as a complication you can no longer get a boner.

There is a ligament that can be relocated to make a flaccid penis appear larger, but there is no enlargement surgery.
