Finally, Penises will not escape their fate that easily anymore.
Gone (potentially) are the limitations due to (mostly) the Male genitals in VAM1 only having 3 bones / joints to allow curving and penetration (Base Penis, Mid Penis and Penis Tip, because the Glans doesn't even count as an actual joint as surprising as it seems). Which means the default 3 'main' colliders of the Male Penis correspond to how limited it truly is (the Tip collider is only there to facilitate the opening of the Female mouth by colliding with the Female mouth's own colliders).
Basically your Plugin is attempting to act like a virtual 'extra bones' / 'extra joints' addition to the limits of the default Male genitalia. So this is beyond amazing because if there's one thing I am often frustrated by in VAM1 it's indeed the _very_ high degree of limitations when it comes to Blowjobs in general (especially with large and long dicks).
Keep in mind, however, that adjusting the Female's own Colliders would still be required by the user in order to make big schlongs work properly (talking from experience; I probably spent more time editing colliders with ColliderEditor than actually 'playing' VAM or even having fun doing my renders and posing characters). The Penis clipping through on the sides and back of the Female head is a sign of insufficient Head, Face, Jaw, Cheeks, Throat, Back Head colliders Radius, Length, and Positioning. But that will be up to the users to adjust literally on a per-character basis (there's no such thing as a "universally good" Colliders setup that would fit every girls scaling and shapes out there, it has to be done manually, for every single characters involved, it's a long process but it's required).
Anyways, I have no words to describe this, this is basically THE thing I wanted to see the most happen for VAM1 (fixing those darn stubborn blowjob situations with dicks ever so slightly bigger than a twig).
