While I agree that it's rather unlikely that just sex is the trigger (and elaborated quite a bit on it over in Misk's blog), I wouldn't bring Jellal into this discussion. He was almost assuredly taken out by August rather than Larcade.

For one thing we saw him close to being defeated last chapter and for another he didn't have that stupid, overly satisfied look on his face that all the others showed after being knocked out.
