If you're like me, you like watching your Vam girls taking big dicks, but it's annoying when those big dicks affect and collide in ways that look terrible and break immersion, seeing their anus stretching and gaping during vaginal sex and often so wide you can see the dick in their pussy... through their asshole... 
So here's a handy plugin that helps control unwanted soft physics anus physics especially during vaginal penetration, while still preserving soft physics and collisions for labia, vagina, etc. Also contains some UI settings to tweak and toggle firmness and/or colliders.
Choose either the person or session/scene variant of the plugin and load them and it should work immediately. Compatible with most other genital physics mods (mostly tested with Skynet's suite of plugins). Likely has minor incompatibility issues to other collision tweaking mods like AcidBubble's Collider Editor, though testing has shown the two plugins can coexist, but this one overrides a couple of minor colliders that Collider Editor also reveals for tweaking, but for 99% of cases shouldn't create any harmful conflicts, especially since anyone using Collider Editor to tweak those same specific colliders probably is looking to achieve the same affect that my plugin does anyway.
