Threesome

A threesome is a sexual encounter involving three people — a common entry point into the lifestyle, most often as MFM or FMF.

A threesome is a sexual encounter between three people and one of the most common first steps into the lifestyle. The two best-known configurations are MFM (two men and a woman) and FMF (two women and a man), each with its own etiquette and appeal.

Couples often explore a threesome with a trusted single — sometimes a bisexual woman affectionately called a unicorn — or with a friend. Clear conversation beforehand is essential: who does what, what is off-limits, and how everyone checks in during and after.

The healthiest threesomes treat the third person as a full participant with their own desires, not a prop. Generosity, communication and aftercare turn a one-off fantasy into a genuinely good experience for all three.
