Antedating? of "shot his wad" 1896

[Sam Clements]

If I missed an earlier cite from the archives, sorry.  I DID search.

OED has 1914, DN.

NewspaperArchive has a 1900 use.

ProQuest yields, from the LA Times,20 Aug. 1896, pg. 6  A story about Wm. Jennings Bryant.  (reprinted from the San Antonio(TX) Express)

<<Mr. Bryan, in the language of the hoi polloi, has "shot his wad." From an oratorical point of view it fell short of the expectations of the people.  It brought down no roofs and inspired no crowds to frenzy, likewise it captured no nomination.>>

P.S.  If anyone can cite the first use of the term in a sexual connotation, I would be grateful.
