My father taught me to rub the male parts of the rod on my nose. Apparently just enough natural nose-lube is transferred, without being too much, to allow separation when done, but not enough that the parts fly apart when casting.
Apparently, stuck rod sections has been a problem for many decades. You'd think one of the brighteyed enjinears at rod companies could figure out a locking system which didn't interfere with the cast, but would eliminate the sticking problem.
Wasn't it Fred Bear who "invented" the compound bow which IIRC was decried as too complex and "unmatural" at the time, but is now pretty much standard?
And I'm reminded of the supposed remark by a razor blade maker regarding electric razors: "What? You want to put a motor on a razor? Why, you'd cut your face to ribbons!"
Incidentally, a quick application of moderate heat might work pretty well. Quick, so the female section expands just a little without the male section getting warm.
