[Spider-Man + MCU] Spider-Man can stick to surfaces with his feet and hands. Does he ever use this while fighting hand to hand? Make bad guys' fists stick to his palm?

also in Homecoming, why would he stick his backpack near street level?  wouldn't he put it in a "spidery" spot just like momma spiders leave eggs?  up high somewhere, outta sight in a nook?

and why wouldn't aunt may know he snuck in the window the night Ned discovered him?  its not a huge apartment.  u cant really come or go without someone knowing.

AFAIK, Spider-Man himself hasn't used the sticking power in an offensive way as you are describing. But his dark and edgy clone, Kaine regularly did. He'd intentionally use the adhesive power of his hand to brand enemies by ripping a layer of skin off their face. The handprint scar left behind was referred to as the 'Mark of Kaine'.
