Well...speaking just of the Reelmagik, perhaps. I've heard cis women say that it feels the same as a cis guy's dick. But you'd probably have to make sure shedidn't reach between your legs, or look too closely, cause yeah, those parts might still be visible. But if you haven't taken steps towards transition, you'd have (I assume) breasts to hide, more female features to compensate for (like a more hairless body), etc, and that might be an issue more than the Reelmagik. It could maybe be done but chances are, if a woman is straight and has been with cis males, she's going to notice these things. Further into transition, probably not.
As for morality...I've never really come to a conclusion on this, tbh. For me, it's not really a moral issue, but a safety issue. Sure, you could get away with not disclosing, perhaps, but pre-op, something's going to come up eventually, and who knows how someone could react? And how many lies would have to be told to hide physical features that may not seem entirely normal for a cis male? Is it worth the chance?
