Well, I’m not going to pretend stuff’s not going to get real weird for a werewolf, but I can clarify some of the orbital mechanics a bit.

First of all, the moon still has all its normal phases from orbit and in pretty much the same durations. For the moon to always be full, you would have to be permanently between the sun and the moon, which is not where an orbit will typically put you. A couple ways you could do this: You could orbit the sun instead, or at least orbit closer to it than Earth does. From Venus’s orbit, both Earth and our Moon are always “full”. You could set yourself up at a lagrange point between the Earth and the Sun.

The other simple way you could achieve an always-full or at least frequently-full moon is to get into what’s known as sun-synchronous orbit.

The simplest way though, might be to just land on the Moon’s surface. The terminator between day and night on the moon’s surface only moves at about 9.6 miles per hour, even slower the closer you get to the poles. An athletic werewolf could probably jog to keep up, and stay permanently on the “full” day side.
