It is very common to experience these issues, and both are highly treatable. Watery semen is often temporary and can be caused by frequent ejaculation, mild dehydration, or diet. Staying hydrated and consuming zinc-rich foods can help improve consistency. For premature ejaculation, behavioral techniques like the 'start-stop' method are highly effective. Medical options include over-the-counter desensitizing sprays containing lidocaine, or prescription medications such as selective serotonin reuptake inhibitors (SSRIs), like dapoxetine. I highly recommend consulting a doctor or urologist. They can rule out any minor underlying causes and safely guide you toward the best treatment plan for your body.
