Does masturbating a lot affect your body stamina?

Masturbating is a physical activity, like exercise. So you burn calories, and when you're done, you might be tired. If you do it a lot, you will be more tired, but you are also building up your stamina in the long run. Like, if you did it 10 times a day, you'd be really tired on the first day...but after a year, you'd be used to doing it 10 times a day and not so tired.
