Passionate Love Making Session(s) (pronounced P-L-M-S or plumbs): Periods of time devoted to cuddling or making love. Not necessarily intercourse but any emotional act that involves two partners simultaneously displaying affection for one another. The key in a PLMS is the emotion and/or passion (as per the first word in the acronym).
