As you mentioned that you are now 20 years old and erection is a common thing, while when penis is erected naturally testicles (balls) become tight, so need not worry. Still you think you have any problem without any hesitation consult a psychiatrist and get his opinion as physical examination is very important. Good luck. </s>
