<s>[INST] I am a 27 years old male, i will be married after 3 months, i have been doing masturbation for last 10 years regularly, despite this i am well healthy but there are some doubts in my mind regarding my penis size which is 5 inches when erected, pre ejaculation problems may be occured in future after getting married, and when i ejaculate less volume of semen. and most stressful doubt is whether i have amble sperm count in my semen. how can i check this before marriage. i want to cure my all problems before marriage. i want to be internally strong as stud before marriage. PLEASE GIVE YOUR SUFFICIENT ADVICE THANK YOU [/INST] Size of penis doesn't matter. Count of sperm can be done at any lab and get done complete sperm examination including count. Even if 40% sperms are actively motile, you do not have to worry. You need little counselling, medicine is secondary. For any other thing like becoming stud please get the Ayurveda doctors help including me. Ayurveda has pioneered in aphrodisiac and rejuvenates group of medicine giving immense sexual strength, but you can't generalize the treatment. Selection of medicines depends on some more info and history. If you agree, ask through direct question please. </s>
