I have a small rice grain sized lump on my right testicle. when i squeeze it a small rice grain sized object comes out. this object is usually either black or beige in color and firm. every time i squeeze it out it comes back in a few months?

It may be associated with like hair follicle gland that may be of no consequence; however you may want to have it evaluated physically by an experienced clinician, probably a dermatologist, so you could be certain of what it is, the cause, and appropriate management of it.

This sounds like a sebciosgland sinus and dried secretion comes out. If persistent pl see a Urologist and have it treated.
