Is it possible to dislocate a testicle?

I was masturbating then I look down and the left side of my scrotum was sorta flat so I go to feel it then my testicle was gone.I feel down and see a bulge almost on the crease of my leg and automatically knew that was my testicle.I push it back up and it happily stood there with no pain or anything.This happened like 3 extra times.Should I be worried because I wonder if I close my leg and I squish a testicle and that fact scares me.Advice or solutions.
