I mean "forced", as I think PH did, in the sense of "the being that was forced did not want to do it". The cases of beetles that get their heads bitten off after mating with a female wouldn't be a relevant example, since, in the appropriate sense, the male seems to want that.
But then, if resistance is part of some test, than PH's example wouldn't be relevant anyway.

The full thing reads like a flash tour of OB/LW, except it was written in 2001.
