Co-ed Missed Base

[UmpireErnie]

It is no different than the scenario with two outs and bases loaded for a female batter who draws a walk, and R2 on 2B fails to touch 3B.

A proper appeal will result in the third out and the run does not score.

There is no "exception" for the runner to not have to touch the base he/she is forced to just because the force was made by a male batter being awarded two bases on a walk.

P.S. In my experience most coed SP teams will have no idea they can appeal this. You and your partner (if you have one) will be the only ones who know. Pause long enough to make sure the defense will not surprise you with an appeal.. as soon as it is clear they will not, exit the field the game is over.
