Orgasms of 20 minutes or more are possible.
Tantric sex specialist Donald Wait says the reason most couples don't reach their full sexual ability is as a result of unbalanced chakras.
He notes that our fascination with social media has resulted in losing our sense of self and touch.
Wait runs an unconventional alternative healing spa called Shakti Gardens in Linden, Johannesburg, that teaches couples how to have their best sex.
He points out that his practice is not an escort agency or a "happy ending" institution.
"I've had clients coming here having misconceptions about what we do. [During a session] one client demanded his wife strip naked but I told her to relax and keep her panties on. He also tried sticking his fingers up one of the female therapists. We run a respectable business. One where we teach people how to reach their sexual peak and respect their sexuality using their seven chakras - which are our centres of energy. It's not about jumping at everything you see."
Wait, 64, opened the business in the 1990s after studying the art of Swedish massage. He went on to study other disciplines and confidently states that he can help couples attain sexual orgasms of 20 minutes or more.
"We have various sexual-enhancing treatments - couples sensual massage, sexual energy massage, sensual healing and expanded orgasm. We start with a counselling session and the client's fears and desires and needs are ironed out. In the therapy rooms, I will often massage the woman while her partner watches and learns. A female therapist will massage the man. We teach techniques for them to practice at home. We teach them breathing techniques and how to shift negative energies from the seven chakras.
"When our sexual energy is not in tandem, our other chakras will be out of balance. This results in having other stresses at work and home and bad relationships with our children."
Wait, a born-again Christian, says he takes on couples of all faiths, even atheists who want to reach their sexual peak.
"I've had a black couple well in their 50s who were struggling intimately. Over the years they grew apart as the kids were always at home. Now they have the whole house as their bedroom. After only one session they both reported that using our techniques their sex life has improved."
Wait says the secret lies in seeing lovemaking as a meeting and merging of souls.
"We teach our clients to kiss each other with their eyes open. It's about heightened foreplay, massaging [and] stimulating each other through touch. It's not only about penetration - that plays a small part. Some clients frown upon oral sex. We teach them the magic of it.
We also teach women how to hold off the male's ejaculation and prolong the intimate session. I've had clients report orgasming for up to 20 minutes. It's experienced not only in the genital region but throughout the body," says Wait.
