Truth is not always fun.
Seriously though, what is the basis for the Electra/Oedipal complex and penis/womb envy? If somebody is claiming I have secret urges I don't really know I have, and I can't see how that is applicable to myself, they're going to need to explain how they know that I have those.
Otherwise, I'm inclined to believe that these theories are being used to prop up or support some other theory.. that the truth of them is irrelevant because they are too useful. Not that you're doing that. I just haven't seen anything that suggests otherwise.
