The meaning of this glyph appears intuitively obvious: the「person」cannot get out of an「enclosure」and is CAPTIVE, or in QUARANTINE when diseased or infected. Or,「person in orifice」who is CAPTIVATED by sexual pleasures. Recalling that「person」is comprised of「erect and taut」when added within a「mouth, orifice」the erection is clearly captured, exposed to great danger at any moment, and in dynastic China this was the job of a SLAVE, a person ENSLAVED who was sold when quite young as a service provider or concubine. If considered from the perspective of a wealthy and powerful master, the whole idea of sexual SLAVERY is「to enclose a man's taut erection in a mouth or some other sort of orifice.」And conversely, it goes without saying perhaps that an「adult male person wholly within an orifice」has been made a CAPTIVE of sorts, who 'might as well face it he's addicted to sex' as it were.

　「Historical accounts from the 18th century indicate that adult-child sex (particularly same-sex pairings) were an accepted practice in China, Japan, Africa, Turkey, Arabia, Egypt, and the Islamic areas of India (Trumbach, 1977).
