Every time I start to take PM for a bit, I seem to lose the desire to feminize or even to continue taking PM within a few days... so I'm wondering if it's satisfying my brain that fast, or if I'm just getting concerned about my ability to present as a male.

I think it depends on how you feel while you're on pm. If you feel you've achieved the mental balance bryony is talking about, I'm inclined to favor the former. If you feel anxious and restless, I think the latter is more probable.
