Well firstly, punishment or practicality, that little boi clit needs to get locked up tight in a cage and not be allowed out without permission. It’s the big advantage trans denial sluts have, you can get it all locked up – no getting out for you:
Awww, poor baby…
Then for public, a nice fat butt plug would suit the situation I’m sure. Imagine how much it’d make you leak.
See my toy recommendations page for some good ones (and Lovehoney do cock cages too – start with the CB6000S in most cases).
