Is there any easy technique written in Bhagavad GITA or any religious books to control lust/self-pleasure?

The quickest and easiest way is control of diet or aahahara as it is known in Sanskrit. There are two categories from Ayurveda - pathya and apathya. You need to stick to pathya foods. Pathya means restricted. By restriction I mean sattvic foods. One needs to completely avoid rajasic and tamasic foods. These are available by the dozen these days. From a modern contemporary Kali Yuga perspective these are the ubiquitous spicy masala foods and most definitely junk food. You need to figure out a diet which is nutritious and wholesome for you. By sattvic I mean do not starve yourself. A good Ayurvedic Vaidya would be helpful to guide you in this regard.

The BG offers a broad guideline on what the sattvic foods are - Sattvic foods and a modern self realized Jnani has recommended this diet - Ramana Maharishi diet recommendations

Mrs. Piggott returned from Madras for a further visit. She asked questions relating to diet regulation.

D.: What diet is prescribed for a sadhak (one who is engaged in spiritual practices)?

M.: Satvic food in limited quantities.

D.: What is satvic food?

M.: Bread, fruits, vegetables, milk, etc.

D.: Some people take fish in North India. May it be done?

No answer was made by the Maharshi.

Please remember that there is a deity in the stomach - Vaishvanara and this is mentioned in BG - Digesting different kinds of food. During youth and middle age the stomach is able to bear the junk foods we eat. As time passes onto old age the karmic reactions will start to appear.

A predominantly sattvic diet(with some rajasic spices) will have a definite impact on the dream state(which is where the lust/carnal pleasures get activated) i.e. during night. You need to also stop spending time in front of the computer and mobile phone beyond 7 pm i.e. eat early before 8 pm and avoid any internet and mobile after you eat. In ancient India there was no electricity as there is in modern homes. People used to light lamps and the house fire. So food was consumed after the evening sandhya and generally people used to sleep after their evening food or practise their sadhana. If one is attempting to capture the ancient order to make spiritual progress then the value of peaceful sleep for the benefit of the mind must be recognized.

UPDATE

In response to some of the comments that a Nayanmar - Kannappa used to offer wild boar flesh to his deity well if one is going to compare a person who is completely steeped in bhakti(devotion) to Ishwara to somebody who is just starting off on their spiritual quest I will again quote from Ramana Maharishi's advice -

D.: Are there restrictions for the realised man in a similar manner?

M.: No. He is steady and not influenced by the food he takes.

Once one's bhakti is firm and you have made progress on the path then restrictions on diet can be removed.
