Testosterone definitely influences masturbation (er, "how often"). It's the cause, not the effect.
Many scientist types seem to agree that testosterone levels drop temporarily after ejaculation, but that seems to be very short-term.
Beyond that, it's tough for me to find objective experiments and studies that measure the T. levels.
Bodybuilders and triathletes seem to agree, based on their experience, that the other effects of a high T. level are clearly obvious to them when they refrain from ejaculating for a week or two. Yet even some of those extreme athletes flatly deny any personal sign of a reduced T. level after climax.

Testosterone builds muscles. Eat more egg yolks.

Depends on how many you can stomach. Some people take as many as 30 a day.

Well, lots of ways to cook your eggs. Boiling them is only one way. You can scramble, poach, half-boil or make an omelette. Be creative, add some herbs for flavour, or some cayenne pepper or regular black pepper. Good nutrition doesn't have to taste like cardboard. Heh.
