my balls are really tight to me penis?

Do you mean they never hang very low, or they have recently become tighter? Different things cause this. Cold, or if you are stressed. Also if you're sick, sometimes your internal temp. changes, causing your testicles to either draw tight, or hang very loose. Temperature is a cause, so try a warm shower or bath, or warming up some other way. You've noticed they may hang lower normally, after you have masturbated, ejaculated. If you haven't masturbated or had sex with a partner recently, see if they drop lower after you ejaculate- maybe 15-30 min.'s later. No need to worry.

Generally when people think something is wrong, they visit their doctor.

In your case it's supposed to be like that.

theyre probably chilled .. hold a heat gun on them until theyre about down to your knees ..
