「Intercourse with pregnancy and feeling the flow of fluids pumping」in many cases also means TO SAY FAREWELL TO, due to ceasing coital activity while pregnant, or, due to the biological father running off into the wilderness, to due to the need to conduct personal selfies until the father and mother can be back in the saddle again, riding that horse.
　See the various element meanings for all sorts of literal reasons why an APOLOGY, THANKS, or CONSOLATION might be needed or spoken. There are other possible element meaning combinations in addition to those listed. Use your imagination.
　Allegorically: sometimes RECKLESS WORDS are「words」that simply「spurt, shoot out, ejaculate」in a naturally spunky manner, automatically and often without much thought, such as THANKS, APOLOGIES, REFUSALS, CONSOLING REMARKS, or that are spoken perfunctorily or too often, and hence lose their meaning, become trite, trifling, and unimportant. Perhaps words that are as obvious as a「pregnant abdomen」so may not need to be spoken aloud every time, or later regretted but cannot be undone as it were, just as a bell cannot be 'un-rung.'
　To WITHER, BECOME FLACCID seems to relate to one's mood or attitude surrounding an apology, and literally of course after「intercourse with ejaculation」of some sort or another, or how one might feel after hearing RECKLESS WORDS of some personal nature, or after squeezing out a baby when pregnant.「Words spoken that are like masturbation」or thanks for actually getting a hand and/or blow job, or giving one, or refusing to give one, and so on and so forth.
　Without a doubt, the Irish also have knowledge of their own to pass along in these trying times:「Masturbation will not spread coronavirus, especially if you wash your hands (and any sex toys) with soap and water for at least 20 seconds before and after.」Nonetheless and regrettably, unlike in dynastic China, it must be undertaken alone to truly be a preventative countermeasure but still achieve the desired result with some degree of safety.

　The Dutch, too have the same solution—it seems masturbation has become mainstream in the media the world over due to the coronavirus (it has always been 'the main stream' in reality, albeit covertly for most folks):
　「'Don't have sex with your partner if they have been isolated because of (suspected) coronavirus infection,' the RVIM says. 'Sex with yourself or with others at a distance is possible (think of telling erotic stories, masturbating together).'」

　Needless to point out perhaps, but Chinese shamans from antiquity hit upon the same solution as a pandemic preventative countermeasure, honed for ultimate client satisfaction by utilizing naked females with no-longer-integrated feet as masturbatory sex buddies available for short-term rental with erotic visualization of live prepubescent female genitalia engaging in autoerotic stimulation herself, as a solution to the same problem facing us now, but in pre-Internet days.
