I found this on ashram.org and thought it might help us single guys if the sex craving comes up:
Techniques for Conservation of Seminal Energy
Technique: When the sex-centre is stimulated, ejaculation of semen takes place. This method checks it
effectively. If there is a thought of sexual desire in the mind, be alert. Concentrate your mind on genitals and
contract the genitals inwards towards the belly, just as piston is pulled outwards to fill the pump with water.
This is called Yoni Mudra. Then shut your eyes. Meditate, "Now I am looking upwards from lower sex-organs
to the thousand petalled lotuses (Sahasrara Chakra) in brain within my body." The seminal energy flows to
whatever point (organ) the mind is focused on. If you focus the mind on Sahasrara Chakra, the bioelectric
energy, which would have otherwise, been wasted in ejaculation through the activated Muladhara Chakra,
will be sublimated upwards to the Sahasrara Chakra and will be transmuted into Ojas. But mind well. If your
mind is still covetous of sex-pleasure, you will not succeed in preserving seminal energy. But if you practice
for a few days with discrimination and strong will, you will get abundantly its rewards. You will directly
experience that even though sexual desires come with a force of storm, with this technique applied, they
subside within a few seconds.
Another technique: Whenever any strong sexual desire arises, exhale all the air from lungs completely and
retain the breath out. Then contract your belly and take your navel back towards the spinal cord. By
repeating this two-three times, the passion is pacified and you will be saved from seminal discharge.
This technique is very simple but it is a very important Yogic maneuver. Air in the lungs is called Apaana
Vayu. With the strengthening of Apaana Vayu the sexual organ awakens and the mind becomes troubled. By
forceful expiration of air, Apaana Vayu is weakened. So it cannot activate the sex-centre. Moreover, by
contracting the belly and navel backwards, the remaining energy in the sex-centre goes towards the navel.
So there is no more energy left to activate sex-centre and thus ejaculation is prevented.
This technique could be practiced in any place, without spending any money. This technique should be
practiced regularly even when there is no sexual stimulation. It gives excellent benefits.
Herbal aid to celibacy: One can make this Ayurvedic Churna, without much cost at home. Take dried Amalas
(goose berries) the fruits of a tree Emblica Officinalis and grind them into powder. Ready-made Amala
powder is available in the market also. Mix two parts of the Amala powder with one part of powdered rocksugar.
You may get this ready-made mixture from ashram also.
Take one spoonful of the powder with water half an hour before going to bed. This powder thickens the
semen. It also relieves constipation. It restores the balance of Vata (Wind), Pitta (Bile) and Kafa (Phlegm). It
is also beneficial to those who get wet dreams. Even healthy people can take it as it helps in self-control.
Use of Gum: Soak 6 gms. Of Gum of Khair tree (Acacia catechu) in water at night. In the morning take this
soaked gum on empty stomach. If this causes loss of appetite, take a few slices of ginger with lemon juice 5-
10 minutes before meals.
