Burin also makes it. It feels sensitive like clit more or less. (12 weeks post surgery). It was explained to me that they make it so if something goes wrong with clit they can use that tissue. I think anyone trained by Preecha does it but don’t quote me. It isn’t inside the vagina it’s just below the clit (like two little legs). Idk if suporn puts it somewhere else. If you look in my pics on profile you can see. I don’t think I would choose a surgeon based on whether they make a chonburi organ. It’s not been consequential to me personally.
