<s>[INST] Hi, may I answer your health queries right now ?  Please type your query here...I did masterbation very long perod of time ,now i have the problem of no strongness in my pennis,premature ejaculation,dilute semens. Plz tell me the best medicine. I am 36 year old and faty body and good hight. [/INST] Hi, Long masturbation can cause penile Mondor’s disease. Prone masturbation can cause Premature Ejaculation, not the regular method. Kindly share your semen report (since you said diluted), so we can work on the cause. Hope I have answered your query. Let me know if I can assist you further.
