<s>[INST] Sir, I stopped masturbating recently. but i have little problem in that area. During sleep, my penis starts leaking without my concern (it gets bigger on its own and starts leaking while i m having a dream ). However i woke up suddenly and stop it midway, but little amount of sperm already came outside. And also i have a girlfriend, whenever i talk to her over phone , my penis gets bigger and starts leaking cum (actually pre cum). I don t know what to do? How to stop this please help me.! [/INST] helloThanks for query. Based on what you have narrated I would state that you are facing problem of night emission. It is normal and natural at the young age to get night emission due to sexual arousal during sleep and does not require any treatment. It gets resolved spontaneously over a period of time. As regard discharge of pre-cum while talking to your girlfriend it is excessive secretion of mucus by mucus secreting glands located in Bulgar urethra which get stimulated by audiovisual stimulation. This is also normal and fades away once you are engaged or used to have routine sexual activities. Do not worry. This is absolutely normal and natural. Chat Doctor.  </s>
