masturbashame 

The feeling of overwhelming shame and regret that overcomes any and all people during masturbation.

Yeah, I turned off the lights but I still had to stop halfway through because of some intense masturbashame.

masturbasement 

secluded, underground space in your home where you can finally jerk off in peace

"After my wife goes to sleep and I kick all of my guy friends out of my downstairs mancave, I get out my pornos and turn it into my very own private masturbasement."
