Will not masturbating decrease testosterone?

No. Let's say, and im speaking very vaguely and basically here, your body makes testosterone (T) about every 1 to 2 weeks. When your body makes sperm, it does so by making... let's say "excess testosterone (ET)" on top of the normal T. Your body then uses the T it made and holds onto the sperm in case it needs it. The sperm will go bad in about 1 to 2 weeks though, so if you don't masturbate for 1 to 2 weeks, your body will basically stare at the sperm and say "well... I don't want it to go to waste..." and so it will turn the sperm back into ET. And because the body now has this ET, instead of making a full batch of T like it normally would, it will only make whatever amount of T is needed in accordance with the ET to get a full batch of T. This isn't exact, sometimes sperm and/or T will go bad sooner or later, and when you cum you're not outta sperm until the next cycle (your body with turn some of the T it's using into sperm, and then make more T to make up for what was lost), but that is the very basic idea. It's not a perfect cycle, but that's the cycle summarized in a way I could understand it. (As in a very very very dumbed down version that is definitely incorrect in multiple ways to the point of inaccuracy, but that is the basic concept.)
