Hi You didn t explain about your age and whether you have just started experiencing the act with girls or you are an old player in this field (i.e. its a chronic problem). If I assume you in the age range of 18 - 30 yrs, and that you have started experiencing the sex recently, its a very common thing to happen in the initial stage. Such type of youngsters are very common in my clinic and i assure you that PRACTICE WILL MAKE YOU PERFECT. If this problem is a chronic one and happens often then its a matter of little worry and you need treatment. If I were the treating doctor for such case I would treat it as a clear case of Shukravah sritas vikriti and manovah srotas vikriti where, by continuous wrong deeds, a person takes its body and mind up to such a confused state where the control on your reproductive system / sexual organs is lost ( i.e. when to hold and when to release). One of the most common reasons for such condition is his uncontrolled abusive thoughts about sex. The first and foremost medication for such condition is strict self-control and MEDITATION ( start with TRATAK ). Keep your mind involved in healthy thought processes and away from abusive thoughts. Simple food (cow milk should dominate your diet) is of prime importance in your condition and strictly avoid very oily or spicy food. Following herbs and medications will help you.... * Musli powder with milk * Purna chandroday rasa * Gud vasti with mahanarayan taila * Suvarna vang * Pure cow ghee (made by traditional method) Hope this answer would be helpful. Warm regards..... Dr. Ranjeet Sharma (ramgoday@gmail.com)
