Hi
I'm still a bit fresh from surgery (just over a month) but no, there isn't much internal sensation. There's enough to get a sense of what's happening with dilation but as I understand it, it's not normal for natal vaginas to have sensation in there anyway! I mean, your prostate still works so there's that. And, I find there's some slight sensation at the end where the skin graft is. But Chett would've had to do some miracle work with regards to nerves to create sensation down there. That means either moving nerves from one place to another (and thus losing some sensation in the original location) or somehow creating new nerves which just isn't possible at the moment.
All my tissue is sensate so my remarks aren't due to numbness or some such
