Cum Swapping

Cum swapping (or Felching) involves transferring a partner's ejaculate from one person's mouth to another's. Often associated with group sexual encounters, it can also be practiced by two individuals. The act usually begins with fellatio; upon ejaculation, the giving partner retains the semen in their mouth, then transfers it. This transfer commonly occurs through deep kissing, sometimes referred to as cum kissing. Alternatively, the cum can be directly dropped from one person's mouth into another's.
Though cum swapping can foster intimacy between partners, its appeal may have deeper roots. The Handbook of Psychology and Sexual Orientation highlights the symbolic significance of semen, representing sexual power, virility, and the culmination of the sexual act. Engaging in cum swapping may be a way to honor these attributes.
Historically, cum swapping was a term for women transferring semen orally amongst themselves, while Snowballing or snowdropping described similar acts among gay or bisexual men. Over time, these terminologies converged, now collectively referring to the act irrespective of participants' gender or sexuality.
