「Woody and already experienced that, retching, too late to do anything about it」describes becoming re-infected, but not clearly knowing when: ROUGHLY, APPROXIMATELY, GENERALLY.「Woody with retching」or perhaps「screwing emissions from weakened and sick woody」with「tonguing mouth of service provider」and「retch, vomit」was the GENERAL RULE, ON THE WHOLE, BY AND LARGE, MAINLY THE CASE during the days when sexually transmitted infections were even worse than they are today…see the glyph meaning 'regret, rue, lament, indignant' (慨) about ONE'S CONDITION. Not many clients would assent to the subsequent retching and removal of stomach contents without permission, either.
　「Woody」and「too late to do anything about it」suggests a piece of penis being chewed off to mean SOMEONE'S CONDITION, and to REMOVE WITHOUT PERMISSION, to ABSTRACT and REMOVE THE BEST PART as referring to the glans, no doubt…in such cases during the old days the cut woody could not be restored, so IN GENERAL, as the GENERAL RULE, in SUMMARY, only a ROUGH APPROXIMATION can be made of the damages (see related glyphs).
　It is difficult to associate actual「trees or wood」with「retching」nevertheless, perhaps this make-believe story will suffice: some「woods」or wooded area and「too late to do anything if chewed off」to mean REMOVE WITHOUT PERMISSION, REMOVE ONLY THE BEST PARTS as might a lumberjack thief cutting down trees in the woods of someone without permission and ROUGHLY chopping down and stealing the best parts. 'remove without permission' means to ABSTRACT, which extends to SUMMARY…in such cases the cut trees cannot be restored, so IN GENERAL, as the GENERAL RULE, in SUMMARY, only a ROUGH APPROXIMATION can be made of the damages from a timber thief.
