With these elements in dynastic China used as vernacular references to the penis (left) and testicles (right), the fundamental meaning of AN ATTACHMENT was as plain as the nose on one's face.
GREEDILY SELLING SEXUAL SERVICES OF ALL VARIETIES:「happiness」「fully complete」meaning an OBSESSION, TENACIOUS, to EXECUTE A PLAN COMPLETELY, until the last step, and TO TAKE THE TROUBLE TO DO everything desired or necessary and not stopping until fully satisfied, to ATTEND TO BUSINESS until completion. To COMMAND as one might speak to a sexual services provider. The meanings become even clearer after considering the individual elements:「person getting lucky a second time with anal orifice of young sex slave girl」with「fully erect and spurting perfection」also as AN ATTACHMENT of sorts.
One thing about the「good ol' days」in China about which there can be no doubt is that adult men enjoyed having all sorts of sex with the various orifices of very young girls, and that is now why there are societal laws restricting these actions:「dirty yen for female sex slaves and erection spurting fully.」…but this was not against any law back then, so judge accordingly— considering the fact that selling and purchasing very young girls pre-trained as sex slave-service providers, and crushing the bones in their feet to prevent escape and for masturbation, was extremely popular in Chinese human society until 1949 when the communists outlawed it, causing that society to become the most populous place on Earth today. This strongly indicates that such behavior is a fundamental part of human nature, literally, the essence or natural instincts of humans is like that of lions, bonobos, and dragonflies, and not that of sexless spirits and mythical deities. The very reason for both law and religion (same glyph: 法) is to try and change this natural essence of humankind. While not suggesting that such an experiment actually be performed, one must wonder what would happen today under those same conditions in humanity's history, who would profit, what「goods」(品晶孨叕厽刕芔毳姦㐂) and services would be offered again in the marketplace if all the legal, religious, and other societal stigmas and controls were suddenly relaxed or totally eliminated. Note external entries「to take heart」as in literally「grasping a penis spewing various drops」(心), and that all the「names of」items are euphemisms for penis matters.
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.
