Hi, For testicle pain we might need you to get few tests done. Let me explain you about your issue in brief - The issue as described by you above is termed as premature ejaculation. There is a possibility that the tip of your penis might have become hyper sensitive. Premature ejaculation (PE) is when ejaculation happens sooner than a man or his partner would like during sex. PE is also known as rapid ejaculation, premature climax or early ejaculation. PE might not be a cause for worry. It can be frustrating if it makes sex less enjoyable and impacts relationships. If it happens often and causes problems. However this issue is not a major cause to worry as much as there are medications and treatment available for the same.
