Hi, im 16, 165 pounds and in good general health.

I've got a bump/swollen thing in the right side of my scrotum. I have no idea whether or not is connected to my testicle. When temperatures drop, or during masturbation the contractions of the scrotum retract the swollen part and it is almost concealed.

When my scrotum is not contracted the swollen part becomes very visible.

I have had NO pain anywhere with the bump.

What are my symptoms similar to?

How serious is this?

How do you suggest bringing this up to my parents. I could tell my friends, but my parents are thick skulled and don't listen very well.

Suggestions please.. Thanks ahead of time.
