Is the difference in testicular size normal?

Q: I am 20 years old. I have a problem with my testicles, they are not even in size & length. My left testicle becomes small in size after I masturbate and my testicles are not even in length. The left testicle hangs little lower. I never had sex before but I masturbate against my pillow as if it is my partner. I got hurt by a rubber ball when I was 12 years. I had pain for 2 hours, thats all. My friends say I wont have kids because of this. Please help.

A:Difference in testicular size is normal. The size of each testis is 3 cm (in length). Left testis always hangs lower than the right one. You are normal as you have normal sexual desire and desire to masturbate. Your friends will bully you so don't give them a thought. They are as ignorant as you.
