Most SRS procedures in the US dig through until you find the sacrum because that's your suture point (sacrospinal suture)Troons don't have this way of self-pleasure. Infact their "clit" is just a fucked up tiny piece of glans. Some, if not most of the nerves are messed up or outright destroyed in the process. We all know from these posts on r/detrans and r/neovaginadisasters that most of them can't feel anything, or if they do, it's pain. Even if they wanted to stimulate the deep tissue, they'd have to dig in and around their stinkditch to even try to find it, since they made a deflated balloon animal out of their cock. But of course they won't do this because this won't make them true and honest wahmans.
If nerves get in the way who cares
