Weightlifter and sexpert Kim Anami offers six-day retreats in Bali and Mexico, where “life-shifting sex is the only thing on your agenda.” If that hasn’t had you clicking to book already, her Mexico Orgasmic Enlightenment retreat offers accommodation in palm-thatched cabins on the shore of Banderas Bay with sessions in sensual exploration, erotic inspiration and ‘wild exhilaration,’ while her Bali Bliss Retreat uses the land’s fertile energy to allow you to delve deep into your natural rhythms and find raw sensuality. You’ll practice sex-oriented yoga and meditation, learn erotic imagination techniques, and enjoy surprises like sex toys and housemade aphrodisiac truffles delivered to your suite.

Six day retreats cost $8,000 (for singles) and $12,000 (for couples).

This process of sensual awakening requires a fair bit of commitment from couples as it spans two years, with each retreat building on the previous one. Through 8 different retreats, you use Tantra to journey along a path of sexual enlightenment. The program includes focusing on female and male orgasms, exploring kundalini energy and flow, and, at an advanced level, a five-day Darkness Retreat where light deprivation has dramatic effects on consciousness and perception.

The full first year costs $3,157 and full second year $3,318.

4. Contemporary Tantra Workshop, Australia and Bali

Jacqueline Hellyer’s Contemporary Tantra retreats transport the ancient practices of Tantra into the modern world, claiming to combine ancient wisdom with modern therapeutic practices.
