Something in the testicle?
I'm 16 right now and when I was 14 or 15 I went to the doctor and I had a small, soft lump on my testicle (ball). The doctor said it was nothing serious. It was puberty and a few weeks later there was something lumpy and painful in my sac. Now almost 2 years later I still have it.
I’d guess it’s just the inner of the hoden? the hodens feel firm and can be pushed back and forth, at least a bit. I don’t know if you’re insecure, you better go back to the doctor.:)
but on the other hand it is not that
