###Human: Whenever I think of sex,my penis starts secreting a transparent fluid. Is this a normal condition or some disease? ###Assistant: Hello. What you are experiencing is a normal process. Whenever men are excited, the secretions start discharging from penis. The fluid which discharges initially is the pre-ejaculatory fluid (pre-cum). When you masturbate, the seminal fluid is discharged. Slight pain after excitation and masturbation is also normal. It subsides in a day or two. This is mostly due to muscle fatigue. Sperm count can be increased by drugs like Fertisure-M taken once a day for at least 3-6 months. Revert back to a sexologist online for further follow up -->
