Player collision (normal play)

[Bluegunk]

Is there a mod, (or a way) to adjust the player / NPC bounding box or collisions so that the player is not kept away from walls and NPCs' bodies?  I find it weird there is a kind of 10 inch invisible shield that stops my character from colliding with an NPC like folks would do in real life.

 

If it's an XPMSSE adjustment, I could do it, but I don't see anything in the NIFs.  I'm aware there are reasons for collision zones to prevent clipping.

 

Thanks.
